Didja know about the Image Processing Toolbox function bwselect? For a blog post I wrote earlier this month, I wanted a binary image containing only the central blob indicated in red... 더 읽어보기 >>

Back in March I started writing about an algorithm implementation experiment for computing upslope area. Given an "image" whose pixel values are terrain elevations, the upslope area of a pixel is... 더 읽어보기 >>

In a blog comment earlier this summer, someone asked how to find "which labeled regions have a bright spot greater than some threshold?" That's a good question. It can be done efficiently... 더 읽어보기 >>

Since I originally posted my upslope toolbox to MATLAB Central back in August, I have heard from some experts about an issue related to NaNs in the DEM data. Specifically, some data sets... 더 읽어보기 >>
