    Hello Oliver

    with the new JPEG operator released in VA 3.2.0 (See New high speed JPEG operator and examples (VA 3.2.0)) you don't need to generate the header anymore. So there are no specific JPEG functions required in the SDK sample. Simply grab the…

    Hi,
    thank you very much for the quick answer!
    Unfortunately I could not adapt the example to my application.
    I would like to upscale an image of 259 x 218 pixels (12 bit, Parallelism 1) to a resolution of 304 x 256. Could you possibly send me another…

    Dear Sir.


    Do you have C# example of JPEG_GRAY.


    Now, we can work c++ example with LineScan and mE5marathonVCL.
    If we want work on C# , do you have any suggestion.
    (like:Use C++ to compiler DLL for C# to call in order to speed for "generate JPEG header

    The "new line" can be sourced by the "Image_Moments" example. The bandwidth should be around 400 MB/s.

    Hi Cam

    That would be a nice application. The solution strongly depends on bandwidth requirements.

    The most ovious solution woul be the following:
    - store each input image in DRAM using operator FrameBufferRandomRd
    - Use CreateImage, ModuloCount, DIV,…

    Hello,

    how would you implement this?

    For every image a new line (point and angle or point and gradient) is defined and along this line all pixels of this image should be extracted.

    Thanks

    Hi Janek

    In example Scaling a Line Scan Image you can find a design using scaling in x-direction using a lookup table. The difficulty of the implementation is the x-direction as we have to conquer some difficulties at higher parallelisms. In…

    Hi,
    I have a custom made camera with two different chips. Both chips of the camera display the same object area in a different wavelength range. The first chip has a pixel pitch of 15 µm and the second chip has a pixel pitch of 17.6 µm. I have to…

    Dear Danna,
    before changing from higher bit depth to lower bit width with operator "CastBitWidth" I always recommend to use operator "ClipHigh" before. This operators sets all input values above a defined maximum to the maximum value.

    Dear Danna,
    thank you for your question.

  • Dear Silverfly,

    In the log I found:
    • PCIe Performance: PCIe is not highspeed capable
    • Currently trained PCIe speed: Gen 1 x4
    • ... payload size 128
    That at least indicates that 4 PCIe lanes are used, and a PCI payload size of 128.

    The facts above should…

    The point you mention is correct and based on our licensing.
    But technically the ParameterTranslation would a a possible way to go.

    Dear Saito-san,

    You can simply adopt the distortion approach into the scaling details.
