Latest results

As part of my hand tracking project I post these last videos. I believe I reached the top of the performance of the particle filter algorithm.

Unfortunately I want even better results so I should move to more complex algorithms. The problem is that real time performance is going to be much more difficult to achieve.

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.
