- _c_o_n_v_o_l_v_e convolves the input image with a kernel image. Kernel images
- can be created with the program greyscale. To do a convolution, the
- kernel image is stepped across the surface of the input image. At each
- position, all the image values under the kernel are multiplied by the
- corresponding kernel values. The sum of all these products is divided by
- the sum of all the values in the kernel. The result is put into the
- output image. If the -m option is given, the maximum value of all the
- multiplies is put into the output image instead of the normalized sum of
- the products. If the -d option is given, a delta value is calculated
- wherever the kernel is greater than 128.
