A colour map to show differences between images
Tuesday, March 31st, 2009
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.
