Hello everybody I have to find the min coord and max coord of this image. (see the red rectangle of the image) How can I do? I know the color is white (255) I made an algorithm but it is too slow. There is a native method of open cv. Thank you all.

look http://answers.opencv.org/question/64... you can find the solution here if you change the code like minRect = BoundingRect( Mat(contours[i]) ); is suited to you

@ato , there is no official opencv support for visual basic.

@ato, maybe you can abuse some 3rd party .net wrapper, but, tbh, they're all badly maintained, and incomplete.

rather learn python ;) (or c++, even)
