Demo to illustrate simple blob detection (segmentation), measurement, and filtering

Demo to illustrate simple blob detection (segmentation), measurement, and filtering. Requires the Image Processing Toolbox (IPT) because it demonstrates some functions supplied by that toolbox, plus it uses the "coins" demo image supplied with that toolbox. If you have the IPT (you can check by typing ver on the command line), you should be able to run this demo code simply by copying and pasting this code into a new editor window, and then clicking the green "run" triangle on the toolbar.

First finds all the objects, then filters results to pick out objects of certain sizes. The basic concepts of thresholding, labeling, and regionprops are demonstrated with a simple example.

It's a good tutorial for those users new to MATLAB's image processing capabilities to learn on, before they go on to more sophisticated algorithms.

Tested with R2008b, R2009b and R2010a.

System Requirements:

MATLAB 7.7 (R2008b)
Program Release Status: New Release
Program Install Support: Install and Uninstall
