Need help with selfmade Hough transform in formula node

Hi all

I do my own facial recognition system and I'm at the stage to make a transformation of my captured image CAM Hough.

So, if a pixel is not equal to zero; I generate a sinusoidal to-90 ° to 90 ° and calculate the corresponding value with the general formula of Hough. Then for the voting process I increase the value of each pixel by 1.

Now, the exit is just a little more dark, but there is no mutation at all.

I think I interpreted the wrong algorithm or I missed a detail in my code...

Thanks in advance

    Hi, I have a requirement where a message is received at the service of BPEL. The message is essentially a list of 200 or less ProductID.
    The requirement is to break the message coming into smaller messages with a list of 50 each ProductID, and then according to the number small messages call in parallel a service Proxy in OSB.

    I don't know how to write an XSL transformation that could divide the message into smaller messages.

    Commenting on just a habit of property changing the css if you have defined it for the desktop version. Your nav elements are not vertically Center because you have a bottom padding set on them for the office, there are only changes for mobile in your css media query.

    .main-nav a {}

    display: block;

    text-decoration: none;

    / * padding-bottom: 15px;   */

    Padding: 12px 0;

    }

    Change the properties for the .product-images for mobile boxes: you have float attached to them for the desktop version and which cascade down to the mobile version, unless you change in the media query:

    .product-image {}

    float: none;

    Width: 50%;

    margin: 0 auto 20px auto;

    }

    As I mentioned in one of my posts related to your project, you will probably have to make your product images a bit larger. They fill the area once they form a column to width of 768px screen or you could resist transform them to one column until a little more by using a media query extra set at a narrow screen width to evoke this action

  • Need help with image fusion

    Hello

    Before I get to my question, I want to give you a glimpse of the project I'm working on and the aspects that I need help. For a school project, a customer, 94Fifty asked us to create an advertisement that depicts their basketball and could be used in advertising online and in magazines. The 94Fifty of basketball is the world's first "smart ball." It can count how many times you dribbling, the arc of your shot, release time it takes for you shoot, etc. To use the ball, you need an Apple product that can download the application 94Fifty on the App Store, so that this project is done as a collaboration with the company 94Fifty and Apple.

    For my ad, to really capture the idea of being the first smart ball, 94Fifty ball I wanted to mix an image of the texture of the ball of 94Fifty, with the shape and details of a brain, with the slogan being, "A ball that is as smart as you." I have my design buried on, but I'm not sure how to combine the image of the brain with ball should I use layers? How can I remove the pink color of the brain and replace it with the ball while keeping the shape of the brain and the lines creased the brain? Any help and technical that you can give would be greatly appreciated.

    Here are two pictures that I'm trying to mix.

    8376271918_cf0b1b5c4f_o.jpg94fifty ball.png

    I would also try and keep the logo of 94Fifty which is on the ball in the mixed picture.

    Please do not confuse this for to ask me someone to do it for me, it's the exact opposite of what I want, I just need help with what to do.

    Here is a fairly simple method:

    First of all, level of basketball for the type to be horizontal. (Also correct the values of white light - burn at the top left and bottom top right.)

    Mask on white background of the brain and turn the image to 0% of saturation.

    Put the brain on basketball on its own layer. Make the overlay blend mode.

    Using free transform, reshape the brain is greater (rounder), like the basketball, with a visible margin around the edge of the ball.

    -Now, you have a brain in a basketball, but the brain is a bit too subtle.

    Duplicate the layer of brain as many times as you need to get the good contrast (I've duped the layer of brain three times, for a total of four layers of brain).

    You will probably find that you need to use the levels adjustment layers or curves on each layer of the brain, for finer value adjustments. Make sure that each adjustment layer affects only the layer directly below.

  • Need help with a declaration of 'IfThenIfNot '.

    Every year couple I need help with a script statement and these forums have been incredibly useful. Once more, I was hoping that someone out there had knowledge of something I am writing for a form, I need to automate:

    In the jargon of Excel that I try to write to would state so @if (("Subtotal"+"InvestigativeFee"+"PlanReviewFee") > 1000, + 100, + (("Sous-total" + "Investigativ Manar" + "PlanReviewFee") *. 1))

    What I have here is three form named subtotal, InvestigativeFee & PlanReviewFee fields.  The formula in question says it's a 'technology assessment fee"of 10% on the total part of what above mentioned 3 fields but there is a maximum charge of $100 for this tax.  The statement that I wrote above would have worked in Excel (not tested, but generally is the idea).  I was hoping someone mastering JavaScript could help me with a statement that I needed to do this work.

    Hope to hear from someone,

    Warmly yours.

    Try the following in the custom calculation of the fresh field of evaluation script:

    (function () {}

    Maximum package

    var max_taf = 100;

    Get the values of the field as numbers

    var v1 = + getField("Subtotal").value;
    var v2 = + getField("InvestigativeFee").value;
    var v3 = + getField("PlanReviewFee").value;

    Calculation of tax

    TAF var = (v1 + v2 + v3) / 10;

    Set this field to royalty calculated value if less than maximum, otherwise the maximum value

    Event.Value = (taf< 100)="" taf="" :="">

  • I'm suddenly needing help with my browser Firefox (6.0.2)

    Hello
    I'm suddenly needing help with my browser Firefox (6.0.2)

    (OS: I use Windows XP).

    When I open the browser, I don't see is a totally white screen of white, with all the toolbars at the top.

    I know that my physical connections are very good: I have tested the modem, turned the pc market etc and I can also receive/send emails.

    This problem started today, September 8, 2011 and has never happened before.

    Is it a coincidence that Firefox itself to day before I disconnected yesterday evening? Could this be something to do with this particular new update?

    I also noticed that just before I "opened" Firefox, I now get a small box indicating:

    [JAVASCRIPT APPLICATION]
    Handl exc in Ev: TypeError: this oRoot.enable is not a function

    This never appeared before - I hope that it offers a clue has what is wrong.

    The browser not be stuck in Mode safe, said by the way.

    Of course, I can't find solutions to the problem on the internet, I don't physically see all Web sites!
    (A friend sends this request in my name from their pc)

    Any light you can throw on this problem of confusion would be much appreciated. I'd rather not have to uninstall and reinstall Firefox if possible.

    If the only option is to uninstall Firefox and reinstall from your site, I'm also in trouble (I can not see the internet or download).
    In this case, would you be able to send the .exe file as an attachment to my e-mail address? In the affirmative, please let me know and I'll give you more details.

    Thanks in advance.

    One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

    Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

    See:

    Start Firefox in Firefox to solve the issues in Safe Mode to check if one of the extensions of the origin of the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > appearance/themes).

  • I need help with an installation failure to interpret and troubleshoot a Setup log.

    Background: A few years ago, many editors of cinema used Final Cut Pro 6 (also contained in Final Cut Studio 2) for their editing projects.  Shared Apple Final Cut X uses a different format that is not compatible with FCP6.  Sometimes, these editors are called to work on a few historical projects that have been published in FCP6 and need this version to run now.

    Starting with OS X Lion, FCP6 would install not in Lion and thereafter.

    According research by Jeremy Johnston as noted on his blog, he discovered that Apple has inserted a file in the folder CoreServices in the Library folder of the system folder that causes versions the version Final Cut Pro X (and other older Apple programs in the same situation) do not settle.  He suggested changes to this file that would seek to prevent interfering with the installation of FCP6 in Lion, many users of final cut PRO 6 were successful in their efforts to install in Lion and work with it.

    Later in a discussion update on installing FCP6 in Mavericks, HawaiianHippie determined that the simplest way to perform the installation of FCP6 was simply copy this file and remove it from the system folder, install FCP6 and then restore the copied file:

    https://discussions.Apple.com/message/26309669#26309669

    I used this method with success to install FCS2 in Yosemite:

    [click on images to enlarge]

    However, in my attempts to install FCS2 in El Capitan, it fails in the last 5% to install the first DVD:

    First of all, I need advice on how to display an extremely large Setup log in this thread (on MacRumors, it is a method to insert a 'code' in a small box that can be the object of a scrollbar if necessary to read all along).  I am unable to find such a method to post here.

    Then once approved, I need help to determine which component is causing the installation to fail and perhaps this element can be omitted from the installation:

    If this element is not required, then maybe FCP6 can be installed successfully without it.  And if that omitted element is necessary, perhaps a manual method to install it can be determined by pacifists.

    It is my goal to help those who need to install and use FCP6 on their new Macs running El Capitan.

    Here is the post on MacRumors with pre-installed Setup log:

  • Need help with the port forwarding for a XBox remote Streaming

    I have a router R6200v2 and need help with port forwarding.

    I came across this set of instructions for setting up stream port forwarding XBox remotely from anywhere

    http://kinkeadtech.com/2015/07/how-to-stream-Xbox-one-to-Windows-10-from-anywhere-with-Internet/

    I have no idea when it comes to such things and I want to make sure I do it correctly without messing up my existing home network.

    Port Forwarding and triggering Port pages setup look very different from what the guy uses. Can someone walk me through what I do to set up please?

    Hi @varxtis,

    You must enter them in the field for a start external Port and external completion Port. You will need to send individually except for the range of 49000-65000. The steps are as follows.

    1. create a Service name (it could be something else that you cannot use the same service name twice. Ex. XBOX1, XBOX2 and so forth.)

    2. Select the type of service (TCP, UDP or both)

    3 entry 5050 times a start external Port and external endpoints.

    4. Select the IP address of your XBOX.

    5. Select apply.

    6 do the same for other port numbers. To the beach, use 49000 for the external departure Port and for the external completion Port 65000.

    Kind regards

  • Need help with network home using Airport extreme

    I need help with my home network.  I'm not very aware when it comes to all things network.  Here's how my network is currently set up.

    Cable modem to Airport Extreme for Gigabit Switch.  Cables come out of the switch to all areas of the House.  I have 2 other extreme airport connected in other rooms of the House directly on the wall that dates back to the switch.  I hope I am explaining that properly.

    My problem is that this seems to have caused some of my connections cable does not work.  When everything is configured, it has worked well.  All connections in the House worked.  Then we have disconnected one of the extreme airport and moved to another location in the House to have the best wifi coverage.  Since that time, a lot of the ethernet wall plugs are not working.  For example, when I plug in my Macbook Pro in making ethernet in my kitchen, it says connected but it has an assigned ip address and cannot connect to the internet.

    Any help you can provide would be great.

    I would like to get the return tech to help you to...

    But it is likely that something (or someone) has tampered with the settings.

    The layout is fine... but you can cause problems with the network by creating a loop.

    This can happen because the AE you moved is connected wrongly... somewhere in the network it is connected to the switch again.

    Or AE is set to expand wireless... It's FAKE... It will loop the network on the back main EI wireless.

    Unplug the two AE you have that function as extensions...

    Turning off everything else... then it works again...

    Do it in this order.

    Modem... Wait 2 min

    AE... Wait 2 min

    Switch.

    Now check that the network is working properly... power of customers in various locations and make sure everything is good.

    If so, then manually reset the two AE of factory and redo their installation.
