    Hello, thanks for sharing, your code looks great because it doesn’t require additional libraries then opencv’s ones, but on line #15 and #16 there are 2 incompleted include, fixing this error gives another error on ATD, on the compiler i got (No Matching Member Function for call to ‘at’), looks like you have forgotten the , can you provide the fixed code? Thanks a lot and have a nice day!

      Hi Marco,

      Thanks for asking, I found that angle brackets (and code in angle brackets) in code do not show correctly and that caused the problem. The two missing includes are math.h and iostream; and the ATD part is #define ATD at(angle bracket)double(closing angle bracket). Hope this comment helps.

        There was another error on the vector starting from on line 216, they should be vector of Mat object, thanks again and have a nice day!

        • Eric

          Oh yeah, another angle brackets problem. U r right, vector of Mat. Cheers!

  • Marco

    #define ATD at fixed some problem but there are others like “vector rgb1;” vector does not exist…

  • Marco

    sorry the type looks like is filtered by your html tag, the define should look like this #define ATD at

  • Marco

    sorry it’s filtered even in the code tags, i hope you have understood the problem

  • Hi,
    that is a very cool algorithm. Thanks for sharing.

    Just some remarks to your code:
    – OpenCV loads color images in BGR, not in RGB. So the channel variables are labeled incorrectly. But is has no consqeuences in your case.
    – ctime has to be included to use clock()

    The fixed code (also with corrected brackets problem) can be found here: http://codepad.org/PU8ezzdl

    Perhaps you want to include a link to the correct raw code in your post, so not every of your readers has to fix this independently.

      Thanks Dobiasd

    Dobiasd’s link looks dead…
    I posted the working code in a new one:

      Thanks!

      thank you for posting the code

        We we use only rectangular areas and no binary mask is specified?

      Why I can’t process the roi bigger than 100 pixels each edge.
      This line will occur error:
      “Mat A = Mat::eye(height * width, height * width, CV_64FC1);”
      The opencv show the error message “The total matrix size does not fit to “size_t” type”
      Is there anybody know this problem.

      • Richard

        I have the same problem and I think Mat type in OpenCV couldn’t support that large size mat.

    Also what if PosX=0 or PosY=0( in GetB )program breaks?
