I use jsfeat to find the coordinates [x,y] of the 4 corners of a trapezoid in a photo ... successful.
I mainly use Canny and Hough Line Transformation.
So far so good.
But the same javascript code calculate different results (coordinates [x,y]) in different browsers (Firefox, Chrome, Safari). I guess, drawImage is the reason. Because the RGB-value of the same pixel is not the same different browsers?!

Does anybody have experiences with this?
