Reader Uri Pe'er found an old post from 2011 about shortest paths in binary images, and he asked this follow-up question (paraphrased):How can I determine if there is a path from one row to another... 더 읽어보기 >>

With the R2015a release a couple of years ago, the Image Processing Toolbox added the function imgaussfilt. This function performs 2-D Gaussian filtering on images. It features a heuristic that... 더 읽어보기 >>

Until about two weeks ago, I had given absolutely no thought to the possibility of a relationship between MATLAB and Pokémon Go, this summer's worldwide mobile gaming phenomenon. But then I... 더 읽어보기 >>

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... 더 읽어보기 >>

A post in MATLAB Answers earlier this year reminded me that working on a discrete grid can really mess up apparently obvious notions about geometry.User Hg offered an image containing two... 더 읽어보기 >>

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.... 더 읽어보기 >>

I was inspired by ICIP 2015 and by the new graph functions in MATLAB R2015b to write some functions to help experiment with graph-based image processing algorithms. Earlier this week I submitted the code to the File Exchange. Here's a screen shot:... 더 읽어보기 >>

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... 더 읽어보기 >>

A blog reader asked me recently how to visualize the ellipse-based measurements computed by regionprops. The reader wanted to superimpose the estimated ellipses on the image.To refresh your memory:... 더 읽어보기 >>
