This is the first of a few blog posts about object measurements based on a concept called the Feret diameter, sometimes called the caliper diameter. The diagram below illustrates the concept. Place... 더 읽어보기 >>

Before I dive into today's topic, I want to invite you to come back to the MATLAB Central Blogs page in a couple of weeks. Look for something new to appear related to deep learning.Earlier today, I... 더 읽어보기 >>

I saw a presentation last month that mentioned a user request to have the ability to customize regionprops. That is, a user wanted to be able to add their own measurement to regionprops.Today, I'll... 더 읽어보기 >>

A few weeks ago, I wrote about a solver algorithm for the Eight Queens Problem. The post included diagrams like this one. Today I want to show you how I made that diagram in MATLAB. First, let's talk... 더 읽어보기 >>

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 >>

One of my favorite aspects of MATLAB for image processing is how I can use a binary image to index directly into a grayscale image. The technique is called logical indexing, and I'm going to show you... 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 >>

Today I'll try to wrap up my discussion about how aliasing affects image resizing and about how the imresize function tries to prevent it. (This is called antialiasing.) Let me show you where we are... 더 읽어보기 >>
