Detailed Description

ImageViz SoConvolutionWithImageProcessing2d engine

Wherever the formulae below refer to $K$, it is the normalization or automatic scaling coefficient. Set $K$ to 1 if you do not wish to normalize the result.

\[\mbox{and}~ K=\sum_{i=-p}^{p}\sum_{j=-q}^{q}|k(i,j)|~\mbox{otherwise} \]

The SoConvolutionWithImageProcessing2d filter produces a convolution of image $I$ with another image $k$. This image $k$ will be converted into a 1D-array and convolution by this general kernel will be performed. It is only implemented for square images.

If image $k$ is of size $(2p+1)\times(2q+1)$, it is in fact a 2D-array with $(2p+1)$ columns and $(2q+1)$ lines. It will be converted in a 1D-array of $(2p+1)\times(2q+1)$ elements by placing side by side the $(2q+1)$ lines of the $k$ array.

\[O(n,m)=\frac{1}{K}\sum_{i=-p}^{p}\sum_{j=-q}^{q}k(i,j)\times I(n-i,m-j) \]
