v.bounds

v.bounds calculates the bounding rectangle of the non-black areas of the image.


v.bounds calculates the bounding rectangle of the non-black areas of the image. It has some features to improve its performance where there might be bits of noise outside the area of maximum concentration. v.bounds finds the top- and bottom-most lines and left- and right-most columns such that noise_tolerance amount of the image mass is outside the defined bounds. In other words, if noise_tolerance is 0.1, then the starting value for the top will be the line in which the accumulated total of pixel values becomes larger than 0.1 times the total sum of all pixel values in the image. From this initial bounding rectangle, v.bounds works backwards, expanding to include consecutive lines or columns which have at least noise_threshold total pixel value. This tends t
