Connected component labeling – Part 5 39

OK, I've learned an important lesson about this blog: I really shouldn't start up two topics series at the same time. It's too hard to find the time to compose posts on both topics each... 続きを読む >>

Upslope area – D-infinity flow 7

A few weeks ago I promised a series on developing a MATLAB algorithm to compute upslope area. Now I'm ready to begin that project in earnest. First, though, I'd like to comment on the... 続きを読む >>

Connected component labeling – Part 4 26

In the previous post in this series I talked about forming a graph based on pixel neighbor relationships, and then finding the connected components of the graph. Another approach starts... 続きを読む >>

New Student Version of MATLAB & Simulink

A new release (R2007a) of the Student Version of MATLAB & Simulink is now available. Several add-on products are now bundled with the Student Version, including the Image Processing... 続きを読む >>

Photoshop CS3 Extended – and MATLAB 8

[Here's a quick note for you, composed and delivered from the lovely confines of Boston's Logan International Airport. Don't worry, I'll get back to my connected components and upslope area topics... 続きを読む >>

Upslope area – Introduction 2

A long time ago, blog reader Brendon asked me if I knew of a way to compute something called upslope area in MATLAB. I responded that I had never heard of that before. Brendan explained that it was... 続きを読む >>

Neighbor indexing 14

In response to my last post about connected component labeling algorithms, blog reader JanKees wanted to know how to find neighboring pixel pairs programmatically. Prompted by this question, I... 続きを読む >>

Pad values in dilation and erosion 4

Blog reader DKS asked recently why values outside the image are assumed to be -Inf when computing dilation. I thought this issue was worth exploring further because it has practical... 続きを読む >>

New MATLAB Desktop Blog

This is just quick note to tell everyone about the newest MATLAB Central blog. When you get a chance, check out Inside the MATLAB... 続きを読む >>

Connected component labeling – Part 3 37

Let's start looking at connected component labeling algorithms. In this post I want to explain how you can think of pixel neighborhood relationships in terms of a graph. We'll look at... 続きを読む >>
