Last month I wrote about a color gamut mapping course that I took at the Color Imaging Conference in Portland, Oregon. I showed a couple of images in that post, in which I promised to... read more >>

In my earlier posts about dilation and erosion algorithms, I wrote about exploiting structuring element decomposition for improving speed. Today I want to discuss a potential decomposition ... read more >>

Earlier this year I wrote about logical indexing and linear indexing. Now I want to finish this little indexing series with an example of a technique I call neighbor indexing. I've... read more >>

Blog reader DKS asked recently why values outside the image are assumed to be -Inf when computing dilation. I thought this issue was worth exploring further because it has practical... read more >>
