Extracting and stabilizing contours


It's been a busy week. I'm now at the stage of contour extraction. Using my adaptive skin classifier and the samples gathered from the detector I build a histogram model for the hand and extract the contours around it. As you can see it is quite robust and works under different illumination. All these are possible with the assumption that the detector doesn't return a false positive. While HAAR cascades are fairly good at the job they don't have a 0% percent of false positives so I intend to add a Fourier hand validator.
