Hi, I would like to calculate how much a special line in the video is irregularly shifted to right or left. For this I want to compare the line with the adjacent line above by calculating the minimum of the quadratic mean for each shift.
I'm first looking for something like: x:=0; y:=123; diff:= 0; while(x++ < in_w, diff += (luma(x,y) - luma(x,y - 1))²); So the first question is: how to get the luma value of a pixel?
