For my series on dilation algorithms, I've followed my unfortunate custom of dragging a series out way too long. :-) So let's wrap it up with a mention of the last key algorithmic idea... read more >>

This post is another in my series on morphological dilation and erosion algorithms. One of the algorithm techniques used by imdilate and imerode is binary image bit packing. In bit packing,... 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 >>

We looked at the decomposition of different structuring element shapes in my previous post on dilation algorithms. Today let's time some code to how decomposition makes a real difference in... read more >>

In my previous post on dilation algorithms I discussed structuring element decomposition. We looked at the decomposition of structuring elements with rectangular domains. Today I want to... read more >>

This is the second post in my series on algorithm concepts behind the implementation of dilation and erosion in the Image Processing Toolbox. Today I want to talk about structuring... read more >>

Post updated on September 4 based on feedback from Cris Luengo's comment. Today I'm starting a new series covering some of the concepts underlying algorithms for performing morphological... 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 >>
