Research and correspondence - difference between 'Match' and 'geometric model Match "?

I was wondering if someone can explain to me the difference between 'Pattern Match' and 'Geometric pattern Match' screws? I don't really know how best to use for my application. I'm search/match small spherical particles in a video gray in order to follow their speed (I do that after subtracting the two following fields to get rid of background motion artifacts).

Which should I use?

Thank you!

Hi TKassis,

1. you can find from this link for the difference between these two,

Pattern match: http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_match_pattern_3/

Geometric game: http://zone.ni.com/reference/en-XX/help/370281P-01/imaqvision/imaq_match_geometric_pattern/.

2. I always prefer the match pattern because of its speed of execution and incase of correspondence to the geometric model that it took a lot of time to match your result. You can find in the attached figure for the same image with these two run time algorithm.

  • geometric matching: difference between the scores and correlation

    Hi all

    What is the difference between the scores and correlation in geometric correspondence?

    Hello

    the correlation score is based on pixel intensities while the score of the geometric game also considers the characteristics of the geometry. See the Concepts of Vision or (geometric matching-> discussion).

    I hope this helps.

  • difference between functionality and corresponding geometric base edge

    Can someone help me with the difference between a function and a corresponding based edge geometric model?

    I understand that:

    o geometric based function corresponding directly uses the intensity of pixels and reason for research and their settings

    o edge based geometric matching first calculates the gradient of the image and then uses this gradient to find features with generalized Hough transformation...

  • Differences between archiving and off of a qualitative research within the Admin Data Toolbox.


    Hello

    Can you please let me know what could be the difference between archiving and the deactivation of the Qualitative research in data Admin Tool Kit.

    Thank you

    Rohini M

    When you idle or archive anything it is no longer available for selection.   The difference between inactive and the archives, it's inactive items still appear available for the fine items while searching of archive will not be.

    Allows so that you have the following to say:

    List A

    -Article 1

    -Article 2

    List items

    If you were to inactivate the point 1, end-users is more would see can be selected when you use the extended qualitative attribute.  However when they are looking for specifications based on the extended attribute, they would still be able to select 1 point, whereas they could find objects that this value was used. If you archive Item 1, end users should display it no longer available for selection from anywhere - including research.

    Lists

    If you were to inactive or archive the whole list, you would see is no longer available for selection when the establishment of a qualitative research of extended attributes.   I don't think that there's nowhere you can search for extended attributes by the list of research currently out of the box so that they would act similar.  Is there a place to find attributes extended by the search list and then he would follow the same rules as above.

  • What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

    I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

    AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

    Mesh

    • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.

    • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient

    • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.

    • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

    Ports

    • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.

    • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

    Problem solvers

    • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.

    • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.

    • Several AXIEM processes are multithreaded as EMSight.

    Speaker

    • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

    I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

  • Difference between the G20 and G25 models

    Hi people!

    I searched your laptop and I was amazed by the Qosmio.
    When I was going to order it, I noticed that there are many models of the G20 with different specifications. Also, I found G25 on internet research and found no difference between the G25 and G20 except receiver TV G25 is NTSC and G20 was released on March and G25 was in June. Instead, they have the same specifications for the hard drive.

    I live in the Portugal and the model Qosmio I can find that this is the G20-118. I was looking for the model that has 2 x 100 GB SATA HD, but cannot not thought about it.

    Internet research I found Qosmio G20-111 which has 2 x 100 GB SATA HD, but on the web page mentioned that it was a Pentium III processor (ridiculous, isn't?). I was looking for more reliable information.

    Already searched for toshiba pages and found no specifications for all models I found 490LS on the research on the web as the G20 - 102, 105, 106, 108, 109, 111, 118, 123,...

    Can someone help me with this? Are there any reliable web page where I can see the differences between the models? is there a .pdf or anyone who can please give me some advice?

    Money is not a problem at this time to acquire the laptop, I'm looking for only the laptop performance more!

  • What is the most important difference between 3D Picture control and controlling the display of Simulator

    I want to create a simulation of 3D on the front panel, and I see that we can use a 3D image control or a display of Simulator control. It seems that each of them can be used at the same position. What is the most important difference between 3D Picture control and display of Simulator?

    Hi sfh1,

    You are right, I found examples of Robotics that use 3D photo control and display Simulator control to display a scene 3D on the front panel. After further research, it seems that control the display of Simulator adds additional features compared to the 3D picture control. The control displays Simulator allows the user to right-click control during execution and change the background color, draw fashion, draw contact, view the ID of robot, display sensor data, suspension of service Simulator and reset service Simulator.

    More in depth on these options and the display of control Simulator can be found here:

  • What is the difference between the audiobook and podcast?

    I have been in charge of research and research - can't seem to understand what is the difference between an audiobook and podcast?

    They are treated differently on the "rocket"?

    At the end of the PC, the difference is probably only in how works the subscription service.  Podcasts can get updated automatically and old versions deleting automatically with itunes, mediamonkey, etc...  On the "rocket", audibook bookmarking features may work differently, but I have not played with them.  the "rocket" can read DRM from audible .aa files but your rocket must be bu Audible 'authorized' (what happens when you connect the "rocket" to your PC and run the Audible Download Manager).  I never heard of podcasts with DRM, but that's neither here nor there.

  • What is the difference between a version of MAR and the software win7 INKL?

    * Original title: MAR v INKL

    What is the difference between a version of MAR and the software win7 INKL?

    Hello

    Thanks for posting your query in Microsoft Community.

    • What exactly you're talking about when you say, 'Version INKL of Windows 7?

    I'll be happy to answer your query, however, please explain more about abbreviation INKL. There is a version called Office of ink that is used in the Tablet PC.

    Here's the other version of Windows, you can make reference to:

    MAR - Microsoft Authorized Reacondicionador

    A new PC requires a version of windows with a new key license installed if purchased from a manufacturer.

    A refurbished PC is allowed to use an existing product key (2nd hand if you like) as long as it is always delivered with a certificate of authenticity (COA). This is referred to as MAR (Microsoft authorized Reacondicionador) which means that Microsoft allows to use existing keys/licenses products.

    Buy a version of windows means MAR technically you buy a second hand copy - being however, software, so it comes with COST, will make absolutely no difference at all.

    N and KN editions

    The features in N and KN Editions are the same full versions of their equivalent, but do not include Windows Media Player or other technologies related to Windows Media, such as Windows Media Center and Windows DVD Maker because of the limits set by the European Union and South Korea, respectively. The cost of n and KN Editions are the same as the full versions, as the Media Feature Pack for Windows 7 N and Windows 7 KN can be downloaded for free from Microsoft.

    Generations of VL

    VL builds work with VLK (volume license key). Volume license keys can be used to activate multiple installations of the software without a mechanism (for example, a product activation mechanism) controls the total number of facilities. The license for the software is going to impose restrictions on the use of the key. In general, the license will limit the key to a certain number of facilities which must be only the Organization of the licensee and also to place the holder under the obligation to keep a record of the number of facilities, hold confidential and perhaps even require that the holder organization makes available for a software license check check that his use of the key is in the terms of the license.

    Please let us know what exactly are you referring to when you say version INKL of Windows 7, so we can further research and answer.

    Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

  • BlackBerry Leap difference between RHC161LW and RHD131LW)?

    Hello

    What is the difference between these two models?

    Sorry, I don't know. I have no way of knowing with absolute clarity. I can only refer you to the resources through which you can do your own research.

    In general, there is no other difference in the Submodule of peripheral BB10. As a general rule, only radio technologies/frequencies are the differences between the submodels, with all other components remaining unchanged. The main difference is the material of the antenna (to manage all of the technologies/RF).

    Note that the reason for this is that there are simply too many different technologies/RF used in our world to allow any single device contain the necessary equipment to deal with these differences. Remains no true universal "telephone"... as such, the physical device to be so great (so as to contain all of the different material) that it would be unacceptable to the consumer population. Thus, submodels evolved as a method to have the same factor fitness, but of different capacities for the different carriers in the world.

    If carriers unify all and all use the same together smaller frequencies/technology, then the need for the subtemplates would evaporate. But, alas, we are not there.

    Good luck!

  • The difference between the ADR and ADF

    People,

    Hello.   I have implemented PeopleSoft Campus Solution 9.0 revision 5 for a University. I develop the application for Admission online for future student to apply for admission.

    I need to install Oracle ADF (Application Development Framework) or ADR (execution of Application Development) to run my application for Admission online web page for PeopleSoft Campus Solution 9.0, but I do not know the difference between the ADF and the ADR.

    My installations are below:

    Server machine: Oracle Linux 5.10 (64-bit)

    Client computer: Windows XP Professional (64 edition) with the Internet Explorer browser

    Architecture Internet Oracle Linux 5.10 Server:

    (1) database server: Oracle Database 11 g

    (2) the server application: Tuxedo 11 g

    (3) web Server: Web 11 g logic

    (4) browser: Firefox Mozila

    5) 8.53 PeopleTools and PeopleSoft Campus Solution 9.0 R5

    On the download page http://www.Oracle.com/technetwork/developer-tools/ADF/downloads/index.html , there are 2 packages to download:

    (1) execution of the 12.1.3.0 application development

    (2) oracle ADF essential 12.1.3.0

    My Architecture Internet of PeopleSoft as shown above has been working properly for a long time. Logical Web 11g works correctly. It seems that the first 'Application development performance' package also install logical Web server which is not necessary in my machine. In addition, ADR is not free, and we may need to purchase the license.

    Essential because ADF is free and without license fees, I chose Oracle ADF essential 12.1.3.0.0 to develop the application for admission online. I read his paper on http://www.oracle.com/technetwork/developer-tools/jdev/documentation/121300-cert-2164864.html

    9.0 Solution Campus system will be run by a University to do business formally.

    My questions are:

    First of all, what package is right for my application for Admission online Campus Solution 9.0? ADR or essential ADF?

    Second, if choose essential ADF, I have a few questions about the 12.1.3.0.0 ADF to match my installations as below:

    (1) as indicated in the document, ADF 12.1.3.0.0 can work with Oracle Linux 5 & 6 (64-bit) and other operating systems. ADF can also work with Windows XP? Can I install ADF with my Oracle Linux 5 server machine?

    (2) as indicated in the document, ADF 12.1.3.0.0 can work with Websphere Server Application. ADF can work with Tuxedo 11 g?

    (3) as indicated in the document, ADF 12.1.3.0.0 can work with the Firefox browser. ADF can work with Internet Explorer in Windows XP?

    Thanks in advance.

    If you want to use essentials, you must download the package from the essential. ADR is the complete stack where you must purchase a license.

  • What is the difference between OCÉ and (OCP and OCS)

    What is the difference between ECAS and (OCP or OCS).

    For example, I heard that OCS helps with the language

    and the marketing of a product.

    Could this be true as ECAS focuses on how to do things.

    and not so much things to a much higher level.

    For example, how do you set up, how you use it, how do you start, etc.

    Thank you Roger

    Roger,

    OCÉ Doghouse more. These certifications can be more CERT of intermediate or high level certificates. These were specifically developed for the gaps in the certification that did not match our OCA, OCP, hierarchy of the CMO.

    Generally, the CERT of the OCS tend to focus more on implementation. These certificates have been developed for the Oracle PartnerNetwork for areas of certification which specifically serve Oracle partners and qualify them for levels of specialization. These certifications are available for all candidates, but are directed towards members of OPN.

    I hope this helps.
