[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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

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... 更多内容 >>

This is just quick note to tell everyone about the newest MATLAB Central blog. When you get a chance, check out Inside the MATLAB... 更多内容 >>

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... 更多内容 >>

Patrick asked for an example on how to compute distances between objects based on resolution information stored in a file. The TIFF format
is one that can store resolution information, and the... 更多内容 >>

In this series I'm discussing different ways to compute the connected components of a binary image. Before I get into specific
algorithms, though, I need to touch briefly on the notion of... 更多内容 >>

In a blog comment recently, Rob asked about what happened to isrgb. When you run this function, it issues a warning about being obsolete. Rob asked "What were the toolbox developers... 更多内容 >>

Several people have asked recently about how bwlabel works, so I plan to write about it here during the next several weeks.
bwlabel implements an operation known as connected component labeling, or... 更多内容 >>
