integrate

Computes the integral on all points in a square between twocorner points, must have an integral image as input.Operates on each channel separately

start x:

Column containing starting points on X axis for integral

start y:

Column containing starting points on Y axis for integral

end x:

Column containing ending points on X axis for integral

end y:

Column containing ending points on X axis for integral

pixel values

Extracts the pixel values at positions given by X and Ytable rows

x:

Column containing X coordinates of the points to extract

y:

Column containing Y coordinates of the points to extract
