In my 16-May-2016 post about image binarization, I talked about the new binarization functions in R2016a. Today I want to switch gears and talk about Otsu's method, one of the algorithms underlying... read more >>

In response to "MATLAB image display - autoscaling values with imshow," MATLAB Answerer Extraordinaire ImageAnalyst posted this comment:A discussion of the relationship and interplay of caxis(),... read more >>

Last week I talked about displaying gray-scale and binary images. In that post, I showed how to control the grayscale range. For example, the call imshow(I,[0.4 0.6]) displays the matrix I as a... read more >>

I promised earlier to post about divergent colormaps. A divergent colormap is usually constructed by concatenating two colormaps together that have different color schemes.Here is an example of a... read more >>

A fascinating question came to the Image Processing Toolbox development team recently from Brett Shoelson, a MathWorks application engineer, prolific File Exchange contributor, and former MATLAB... read more >>

I'd like to welcome guest blogger and ace MATLAB training content developer Matt Tearle for today's post. Thanks, Matt!... read more >>

I've seen two questions recently about the speed of the fft function in MATLAB. First, a tech support question was forwarded to development. The user wanted to know how to predict the computation... read more >>

Today I was talking to Spandan (a regular guest blogger here) about the history of the Image Processing Toolbox function regionprops. This function is a widely-used work-horse of the toolbox. Many of... read more >>

I'd like to welcome back my fellow MATLAB Central blogger Brett Shoelson for the second in a three-part series on extracting curve values from a plot. You can find Brett over at the File Exchange Pick of the Week blog, or you can check out his many File Exchange contributions. -Steve... read more >>
