Math Transforms of Edge detect, sharpening, ...

Post by Zack »

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 image may be different (lower resolution transform), and it would be nice to know more about the math so I can get it to work on the actual image. Thanks alot.

you can find some kernel in udf-def.dat file
Result is different between small preview and original file
