For my series on dilation algorithms, I've followed my unfortunate custom of dragging a series out way too long. :-) So let's wrap it up with a mention of the last key algorithmic idea... 続きを読む >>

In my previous post on dilation algorithms I discussed structuring element decomposition. We looked at the decomposition of structuring elements with rectangular domains. Today I want to... 続きを読む >>

Transparent graphics objects can be used effectively to visualize image processing concepts. Two particularly useful techniques are: Highlighting image... 続きを読む >>

Some nonlinear image processing operations can be expressed in terms of linear filtering. When this is true, it often provides a recipe for a speedy MATLAB implementation.... 続きを読む >>

Here's a very common question we receive: "How do I process a set of image files in a directory?" I first posted an example illustrating "batch processing" of a set... 続きを読む >>

Several questions I've seen about bwlabel are about finding the correspondences between object labels in two images. In other words, if a particular pixel is in the foreground in two... 続きを読む >>

The three most common questions I've been hearing about bwlabel, which is used for labeling connected components in a binary image, are about Search order ... 続きを読む >>

I've received several questions over the past months about the search order for the function bwlabel and whether it can be changed. Today's post discusses the search-order issue, how useful it... 続きを読む >>

Blog reader André recently asked me how to count the number of times each color appears in an image. One short solution involves optional output arguments from the function... 続きを読む >>

I'd like to welcome back guest blogger Stan Reeves, professor of Electrical and Computer Engineering at Auburn University. Stan will be writing a few blogs here about image... 続きを読む >>
