BLOB analysis

I have an 8-bit grayscale image that is obtained after subtracting 2 images.  I enclose the image to the post office.  There are 4 white areas in the image.

I am mainly interested

  • calculate the area of the riegions

  • Number of pixels in height

  • Coordinates for regions of white.

Hello

I responded to the problem in your previous post here

http://forums.NI.com/T5/machine-vision/create-an-image-of-dimension-3969-X-260/TD-p/3090967

This solves the problem?

Concerning

Aveo

  • image of BLOB analysis

    I like this image:

    I need to create BLOB objects for every group that has more than 5 pixels, so I want to extract the pixels that are in each BLOB.

    I could do this in different applications but do not know haw to use in labview

    Glad I could help. The problem is that this case is, you use Machine Vision > detection of form instead of binary > circle detection. The difference is, instead of trying to find particles of circle inside objects, it detects only circular objects, in other words, it determines the shape of all the objects and then decides whether or not it is a circle.  In our case, this will not return any results since we circle shaped objects.

    I had very good results with the detection of 2-3 pixel RADIUS circle, based on the jpeg format, you have set up.

  • How to detect multiple points of laser on the image

    Consider I have a picture with several spots dark bright laser. I want to find the center of gravity of each laser spot and return the coordinates of each spot.

    Currently, I managed to detect an single spot to grab an image, adjustment of the threshold (threshold IMAQ) and find the center of gravity (centroid IMAQ).

    However, when I have several points of light, this method gives me the center of gravity of all tasks combined. Should what technique I use to detect the center of gravity of each individual laser?

    Thanks in advance.

    Try to use blob analysis.  Make a fast threshold, which should give you a place for each laser.  Blob analysis allows to get the center of each BLOB.  Use the function of Center of gravity to locate the exact gravity Center, if the center of the BLOB is not good enough.

    You should be able to save time by recording the previous values of the center of gravity.  Lasers are moving very quickly, their new locations should be near their old location.

    If it is still too slow, understand what part takes the most time.  If it's the center of gravity, I am able to suggest other ideas.

  • Save with the smart camera

    Hello

    I have a problem with the help of a 1742 smart camera

    In a while loop I acquire an image, perform a simple blob analysis and I want to save for each acquired image, the coordinates of the blobs.

    The problem is that labview give me an error when I try to save the file

    There is the code used in attachemnt

    can someone help me?

    Thank you

  • Reg: Analysis BLOB and download in rows and columns-

    Hi Experts,

    I have a requirement, that I met him, but isn't a very good approach. You will appreciate your suggestions on this.

    There is a column of type BLOB, when a CSV file is downloaded using the interface of the APEX. I am the analysis and break the BLOB i.e. CSV values using regular expressions and insert rows in table for later use in n columns.

    Note: The downloaded CSV file assumes the maximum of 50 columns.

    Like this:


    -/ / Convert BLOB on the CLOB type

    () DBMS_LOB.converttoclob

    v_clob, v_blob,

    DBMS_LOB. LOBMAXSIZE,

    v_dest_offset, v_src_offset,

    v_blob_csid, v_lang_context, g_msg

    );

    -/ / Find total no of records

    l_length: = DBMS_LOB.getlength (v_clob);

    l_records: = (l_length-LENGTH (REPLACE (v_clob, CHR (10))) + 1;)


    BECAUSE me IN 1.l_records

    LOOP

    v_pos1: = CASE WHEN (i = 1) THEN 1 ELSE (DBMS_LOB. InStr (v_clob, Chr (10), 1, i-1)) END;

    v_pos2: = CASE WHEN (I = l_records) AND (l_length) ELSE (DBMS_LOB. InStr (v_clob, Chr (10), 1, i));

    v_substr: =.

    (BOX WHEN i = 1 THEN

    DBMS_LOB. SUBSTR (lob_loc = > v_clob, amount = >(v_pos2-v_pos1), offset = > 1)

    ON THE OTHER

    DBMS_LOB. SUBSTR (lob_loc = > v_clob, amount = >(v_pos2-v_pos1)-1, offset = > v_pos1 + 1)

        END );

    (on Oracle 11.2.0.3.0)

    Writing the BLOB in the disc and using an external table are likely to be more effective.

    Disadvantage: you must serialize the process to ensure that simultaneous sessions do not alter the location of the external file.

    A function in Java-based pipeline could also be an option, or even a custom parser csv (free regex) written in PL/SQL.

  • Oracle 9i excerpt/analyse XML in BLOB

    I have the table with the Blob column. In the column of the blog, I have data XML (see below).

    And of course any fix untested untested code made things worse... * sigh *. DBMS_LOB.substr has an agenda of setting different than the regular substr.

    DBMS_LOB. InStr (xmlstring, '') + length ('')) GetTest

  • Unpacking error when you try to use UTL_COMPRESS. LZ_UNCOMPRESS to get the text XML 'payload' of a BLOB field

    Hi, really appreciate any pointers anyone may have with what I'm trying to do here... the crux of the matter, I have is the following:

    * Try to get the contents of a BLOB column directly in PL/SQL, zipped/compressed

    Uncompressed data are XML... below is an example quite pinked...

    <? XML version = "1.0"? >

    * I tried a few tweaks to the functions provided here to try to get the data directly into the pl/sql (ideally I would like to be able to enter in a type of XMLTYPE data & query only). However, that's where I'm struggling

    The order of the parameters for the parse_file in the specification and body must match. In your case, it stopped the p_separator parameter (before nom_table_p in spec, but otherway around body) which is the origin of the problem of compiling again.

  • Phot of problem analysis

    Hello

    I have a problem with the app photo with Sierra.

    I 107755 pictures. the analysis of people started

    but he remains arrested with 519 photos

    I tried to fix the bookstore. restart analysis but still stuck to 519 phoos.

    Does anyone have the same problem and a solution?

    Thank you

    Thomas

    How long it has been blocked? You have a very large library so I keep the Mac awake and fed and the Photos doesn't work does not and give him a few days - usually messing slows it rather than speeding it and is a 'restart Yvert"command

  • I can't save analyses after you download Sierra OAS

    I can't save analyses after you download Sierra OAS.

    The "Save" button is grayed out?

    Hello 2014anthony1,

    Thank you for using communities of Apple Support.

    I see that you can not save scans after updating to Mac OS Sierra. I would make sure I can save analysis too, I do a lot of scanning on my Mac. Let's work together and get this problem is resolved.

    I suggest to use macOS Sierra: update or change the printer software, more precisely, that these sections:

    Most printers are compatible with Mac OS. When you add a printer, Mac OS automatically uses AirPrint to connect to the printer or the printer software downloads (also called a printer driver).

    If you can not use a printer that is already added, or you see not the options you want in the print dialog box, you can add the printer again with different or software to print settings different.

    Add your printer with different parameters

    1. Choose the Apple menu > System Preferences, and then click Printers and scanners.

    2. Select your printer from the list, and then click the button Delete .

    3. Click on the button Add and if a context menu appears, choose Add a printer or a Scanner.

      A dialog box is displayed that lists all Hello, IP, printers directory shared, and open on your local network. It may take a minute or two for your printer to appear.

    4. Select your printer, when it appears in the list, and then do one of the following:

      • Use AirPrint: Click on the drop down menu, then choose AirPrint (or Secure AirPrint). If AirPrint is not on the shortcut menu, the printer does not support it.

      • Use a printer software installed on your Mac or downloaded from Apple: Click on the drop down menu, then choose Select software.

      • The software to print a file on your Mac: Click on the dropdown menu, then select other. Select the file, and then click Add.

    Update your printing software

    If your printer is not how to use AirPrint, you can use Software Update to download the latest version of the software. If you don't do this, you see a message that software is not available when you connect your printer.

    • Choose the Apple menu > App Store, and then click updates.

      Install the software updates that are listed for your printer.

    • If the software for your printer is not available using the software update, you can contact the manufacturer for more information. Maybe it's that your printer is not compatible with Mac OS. To check, see the article Apple Support printer and scanner software available for download.

    If you install the printing software you don't have Apple, printing software can not be updated automatically when you use the software update.

    Let us know if that helps. We'll help you get through this.

    All the best!

  • iOS 10 bed - sleep analysis does not

    I use the new feature in iOS 10. The first night, he showed me a graphic analysis of sleep. But every other night, the alarm sleep wake up properly but there is no data from the analysis of sleep. The days are just empty.

    I did disable the feature or did something else to change the settings. It is simply not show me how long I slept.

    It is a disappointment - I was really looking forward to this feature. Anyone else having this problem, or am I missing something?

    I wonder also how works the time of sunset. How she not analysis sleep? With the right movement? Should it be on my bed, or can it be on my bedside table? How this compares to an application like sleep work? I use for several months now, and it looks even better that bed IOS. Sleep wake me according to my cycle light sleeper, or only at the time, I put?

  • My MacBook 12 regularly gets an analysis of needs of Unix executable file names in her basket

    My MacBook 12 regularly gets a Unix executable file named 'needsanalysis' in his trash. Anyone have any idea why? What is it? What can I do to stop what is happening?

    I have two laptops on a an environment MBA 2011 and a 2016 MB and it happens on the latter. Both are on OSX 10.11.6

    Thank you, Colin.

    The executable "unix" just means that it doesn't have an extension for the operating system is not what it is. In addition, the executable bits are defined, so it may have been a case, but this info was lost, too.

    Do you run all software anti-virus on them? I don't know what else would generate something that "needs analysis".

  • graphical analysis

    How to do a graphic logo

    analysis of right to left on the screen in 10.2.3?

    Animation of an object is done by applying keyframes for the parameter to be modified. In your case, you want to set two keyframes for the coordinate x: one at the beginning of your clip, with the object on the left side of the screen and the other to the ned of the clip with your object on the right side of the screen. Open the * system for FCPX and look for the video Animation. If you have no experience in animation control, the notions of keyframes and accelerations and trajectories can be quite confusing.

    Presentation of video animation

    With Final Cut Pro, you can create simple changes to the video over time, such as discoloration of the video of the invisible to the visible at the beginning of a movie. Or you can make sophisticated and precise settings over time, many individual parameters of effects video, transitions, trajectories and so on.

    In Final Cut Pro, you use keys and handles images in Video Animation Editor to edit the effects in time of fade.

    The key Word is the traditional workflow in the animation industry, where only important (key) frames of an animation sequence learned to sketch the movement of a character over time. Once the key frames were determined, an in-between artist drew all the frames between keyframes.

    With Final Cut Pro, you can set parameters to specific values to specific times (represented by keyframes) and Final Cut Pro acts as an automatic in-between artist and in time real, calculating all values between your keyframes. For example, to animate a parameter, such as rotation or balance settings, you must create at least two keyframes in the clip. Final Cut Pro of figures on the value of the parameter between keyframes, creating a movement smooth as the setting changes.
