Detailed Description

Class definition of a method frame for neighbourhood operations using a kernel.

A result image will be allocated with the same size as the source image. The type of the result image is obtained from the HxImgFtorRuleBase via

resulttype of kernelNgb<source,ngbName>

The required type for the kernel is obtained via

kerneltype of kernelNgb<source,ngbName>
