File Information

This simple method can be used to segment locally darker regions in a grayscale image that have a somewhat circular appearance.
demo.m performs a segmentation on the example image recon_test.png.

The method has been used in medical imaging as part of an airway segmentation method to extract the 3D airways. See for details of the full method and for results.
