Math Transforms of Edge detect, sharpening, ...

Thanks for making a great software. Is there any documentation of the mathematical kernels (with subsequent normalizations) for edge detect, sharpening, emboss operations?? I get excellent results in the preview window but not the actual image, so I think the mathematical transform on the preview im...

Re: The three Edge_detect implementations

Thanks for posting the convolution kernels for the edge filters. There must be a normalization step in addition to make the negative values produced by this kernel in the correct pixel range. I've tried to see if a simple linear transform using the max and min pixel to 255 and 0 in the grey scale, b...
