Despite recent appearances on the blog, I still exist! It's just been a little crazier than usual for the last month or so.Anyway ... I'm back, and I'm going to try to wrap things up about image... 続きを読む >>

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... 続きを読む >>

In my 09-May-2016 post, I described the Image Processing Toolbox functions im2bw and graythresh, which have been in the product for a long time. I also identified a few weaknesses in the functional... 続きを読む >>

As I promised last time, I'm writing a series about functional designs for image binarization in the Image Processing Toolbox. Today I'll start by talking about im2bw and graythresh, two functions... 続きを読む >>

With the very first version of the Image Processing Toolbox, released more than 22 years ago, you could convert a gray-scale image to binary using the function im2bw.I =... 続きを読む >>

Twice in the last month, I have read comments about certain problems being intrinsically hard to solve. In a fascinating book I just started to read called Algorithms to Live By, authors Brian... 続きを読む >>

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(),... 続きを読む >>

I was looking at some documentation yesterday and saw something that I had forgotten. When you write a JPEG2000 image file using imwrite, you can specify a desired compression ratio.OK, that sounds... 続きを読む >>

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... 続きを読む >>

MATLAB R2016a shipped earlier this month. It has a new feature that is a personal favorite: the Pause button. Have you ever sat watching MATLAB busily running your code, thinking that it was... 続きを読む >>
