13.3.5 Useful Convolution Filters

This section briefly describes several useful convolution filters. The filters may be applied to an image using either the convolution extension or the accumulation buffer technique. Unless otherwise noted, the kernels presented are normalized (that is, the kernel weights sum to $0$).

You should keep in mind that this section is intended only as a very basic reference. Numerous texts on image processing provide more details and other filters including [69].
