This is a quick sample using F# and Accord.NET to do face detection. The method uses the provided Haar-like feature detection. The results aren’t particularly good, but for little effort it’s an ok start. At a minimum, it does reasonably well at detecting potential regions of interest. For the test images, the best improvements were found when constraining the min/max range based on the known sizes of faces in the pictures.
Primarily, codesuji.com is an experiment. As time progresses, it (like code) will flow in many directions. For the moment, my immediate focus is to bring practical and interesting examples of F# and functional programming to the masses (that’s you).
