Mathematical Morphology and colour images

Sunday, June 23rd, 2013

We recently organized the 11th International Symposium on Mathematical Morphology here in Uppsala. I’m very happy with how the event turned out, and we got lots of positive comments from participants, so all our hard work paid off. We had a nice turnout, very interesting presentations, and lots of discussions. And I’m now the editor of a book containing all the papers presented.

There seem to be several trending topics in the ISMM community at the moment. One of those is the application of Mathematical Morphology to colour images. People have been working on this topic for a while now, and still there is no optimal solution. This year, three very different methods were presented to try and solve this problem. But what is this problem about?

A colour map to show differences between images

While commenting to a recent blog post by Loren, someone linked to this article at IBM Research. I thought it had some very interesting points, and made me think about the 'zerobased' colour map in DIPimage. It is designed to highlight positive versus negative values, for example when displaying the difference between two images. Using a simple grey value colour map it is difficult to determine what exactly is the zero level.
