Abstract:
A method of resizing a digital image, comprising the steps of:(a) providing an M1 by M2 pixel image where M1 and M2 are positive integers; (b) filtering a row of M1 pixels of the image with a set of filter coefficients which depends upon pixel location to yield M1 filtered outputs; (c) discarding M1âˆ’N1 of the filtered outputs of step (b); (d) repeating steps (b) and (c) for all other rows of the M1 by M2 image to yield a N1 by M2 image; (e) filtering a column of M2 pixels of the N1 by M2 image with a set of filter coefficients which depends upon pixel location to yield M2 filtered outputs; (f) discarding M2âˆ’N2 of the filtered outputs of step (e); and (g) repeating steps (e) and (f) for all other rows of the N1 by M2 image to yield a N1 by N2 image.
