| 36 | % Morpology is the the application of various kernals, of any size and even |
| 37 | % shape, to a image in various ways (typically binary, but not always). |
| 38 | % |
| 39 | % Convolution (weighted sum or average) is just one specific type of |
| 40 | % accelerate. Just one that is very common for image bluring and sharpening |
| 41 | % effects. Not only 2D Gaussian blurring, but also 2-pass 1D Blurring. |
| 42 | % |
| 43 | % This module provides not only a general accelerate function, and the ability |
| 44 | % to apply more advanced or iterative morphologies, but also functions for the |
| 45 | % generation of many different types of kernel arrays from user supplied |
| 46 | % arguments. Prehaps even the generation of a kernel from a small image. |
