Hi, Patrik Thank you for your reply. I was referring to real time tracking, and as I noticed supervisedescend is restarting much more frequently comparing to Intraface. Actually, the landmarks...
Yeah, I've seen the discussion #19 and I have to disagree. Actually I think that I've reverse engineered closely the Intraface implementation. First of all, at initialization from previous frame...
You can use Procrustes analysis in order to find rotation, translation and scaling that aligns mean shape with previous frame shape
Similarly, as using still images, only you need to align the mean shape in the initial step using different strategy (based on the shape from the previous frame). The learning...
You need to use transformation that you've found by Procrustes to transform the mean shape as close as possible to the ground_truth/previous_frame shape. Then you need to crop, scale and...
Patrick, it is not a PCA SIFT, since they use default 128 size descriptor per keypoint (8 bin descriptor = 8x4x4=128). The trick is probably in histogram calculation and trilinear...
Also I do not think that using still images you can get all the extreme poses as in video. Face detector can find the face for frontal head pose with...
