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... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

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... 続きを読む >>

As Loren posted yesterday in her Art of MATLAB blog, the R2007a release is available. Readers of this blog might be interested in the minor upgrades the Image Processing Toolbox, the Image... 続きを読む >>

Several readers commented on my recent roipoly and poly2mask posts, and I wanted to follow up on a couple of issues they raised. The first issue is a common point of confusion about ... 続きを読む >>

Last week I wrote about a possible modification to poly2mask that would estimate how much of each pixel is contained within a polygon. The idea was to use a regular 5-by-5 subgrid and ... 続きを読む >>

In December I wrote several blogs about the algorithm underlying the poly2mask function. Basically, the algorithm uses a 5-by-5 subpixel grid and lays out the polygon along the edges of the... 続きを読む >>

Item 1: Digital image correlation for strain measurement The iMechanica web site has an item on a MATLAB tool that applies digital image correlation techniques for measuring material... 続きを読む >>

I started this blog on image processing and MATLAB about a year ago. Shortly afterward, another blogger discovered it and told the world that a blog solely about MATLAB and image processing was... 続きを読む >>
