USAN filter in OpenCV - custom filter

Question

I'm trying to implement SUSAN corner detector in OpenCV Details here.

So far I have the filtering function, but there is a problem, that this is not an linear operation. According to documentation it's possible to use FilterEngine and BaseFilter to write custom filters. There are unfortunately no detail how to implement the filtering function dst(x,y) = F(src x kernel). I'm using C++ and OpenCV 2.3.

Thanks in advance.

A nice tutorial how to implement custom 2D filter based on kernel convolution is here!
