Usage
#include <vips/vips.h>
int im_fav4(in, out)
IMAGE **in, *out;
Overview
im_fav4 averages four input VIPS images, which must be unsigned byte images with any number of bands. This is useful for noise reduction by grabbing 4 frames and averaging them. With 7 bit images this will give quite a convincing eighth bit.
