I have an image sequence (video). I would like to count the number of objects in the image sequence. But the main objective is to count them once, meaning not just in each and every frame, since an object may exist in for several frames. My idea is to count the objects as they exit the screen, because of less occlusions. I am thinking of doing this by scanning the bottom part of the image for non zero pixels.

I have a CV_FILLED binary image (from rectangle function) where I want to do the scanning, then create an instance on an object if abject is found. But this scanning will not be scanning each and every pixel along the horizontal line, just certain sections.

Like we could do it over ranges, say certain columns, then skip by a margin.

A sample binary image I have is attached CV_FILLED binary image. This is an image obtained from the feed. I do not want to count only the objects in this image, but also those that are still coming.

A full picture of detected objects is attached here.Your guidance or constructive criticism is welcome
* I do not want to use CVBlob

    Thx guys. I managed to solve this already. I used small ROIs along the paths of the squares, and found countNonZero() within the ROI.

    I kept on checking with boolean variables to see if the ROI still had the white pixels. If not, incremented counter. Worked well, and I was able to count.

    Thx for your input…
