Pagination or Media Count:
A procedure is described which enables images to be digitally zoomed, smoothed and differentiated. It uses a least squares polynomial fitting technique. This method reduces to the convolution of an array of samples from the picture with a corresponding array of integers. Several such integer arrays are calculated for a variety of array sizes and polynomial degree. Author
