MATLAB image display – scaled indexed images 1

Posted by Steve Eddins,


In my last post on pixel colors, I described the truecolor and indexed image display models in MATLAB, and I promised to talk to soon about a third model. That model is the scaled indexed image, a variation on the indexed image. The function imagesc is often used to display... read more >>

Image-based graphs

Posted by Steve Eddins,


Last time I showed you the basics of using the new graph theory functionality in MATLAB R2015b. Today I want to talk about some functions I put on the File Exchange for making graphs from images. Those of you working with graph-based image analysis algorithms might find them useful. I would be very interested in receiving feedback on these functions.... read more >>

Improved dashed and dotted lines in EPS files

Posted by Steve Eddins,

At the ICIP (International Conference on Image Processing) last week, a customer stopped by the MathWorks booth to chat. He said that he regularly uses one of the File Exchange submissions that "fixes" dashed and dotted lines in EPS files exported by MathWorks. so I spent some time looking into... read more >>
