I'd like to introduce guest blogger Brett Shoelson, who has prepared a series of posts on implementing image special effects in MATLAB. Brett, a contributor for the File Exchange Pick of the Week blog, has been doing image processing with MATLAB for almost 20 years now.... 更多内容 >>

A lot happened in the R2012b for products related to image processing:

A month ago, MathWorks shipped its annual September release, R2012b. (MathWorks follows a twice-yearly release schedule for the entire product line.) Several of my fellow bloggers have already described various aspects of the new release. Today I'll take a look at MATLAB, following my typical practice of highlighting a few changes to MATLAB that are particularly interesting to me.... 更多内容 >>

I'm flying down to Orlando, FL on Saturday afternoon for the IEEE International Conference on Image Processing (ICIP 2012). I'll be doing two workshops there on Sunday and Monday of next... 更多内容 >>

Today's blog post was written by Spandan Tiwari, a developer on the Image Processing Toolbox team. Thanks, Spandan!... 更多内容 >>

Today I'm wrapping up my analysis of the results of my Cody problem on eliminating unnecessary polygon vertices.... 更多内容 >>

Today's post is about this picture, which is from the paper "Classroom Examples of Robustness Problems in Geometric Computations," by L. Kettner, K. Mehlhorn, S. Pion, S. Schirra, and C. Yap,... 更多内容 >>

A couple of weeks ago I posted about how one might want to simplify the output of bwboundaries in order to remove unneeded vertices in the output boundaries. That is, turn this polygon: into this... 更多内容 >>

Today I'm combining my blog post with a new problem submission on Cody. The problem is related to the function bwboundaries in the Image Processing Toolbox. This function traces the boundaries of... 更多内容 >>

Last month I was experimenting with an algorithm in which I needed to construct a set of equidistant steps along a path consisting of line segments. (I'll call this a polyline path, or polyline for short.) Today I want to show you how to construct such a path in MATLAB. Along the way I'll show you the function improfile and give you a pointer to a database of sample range images that I found.... 更多内容 >>
