After some image transform, I obtain these image.
After trsforming the video image I get this stain, which I would like to separate along the red line hand-drawn. I tried with shi-thoman corner detection without getting anything worthwhile. I do not know what strategy to take .... I'm able to filter the little point on screen with findcontour, for exemple and about area contour.
But I have not ideas about how to separe the 4 object along the red line (the desired result ... red line is draw by hands).
regards gfx
