摘要:

Recent \r
years have witnessed the emerging popularity of regression-based face aligners, \r
which directly learn mappings between facial appearance and shape-increment \r
manifolds. In this talk, I will introduce a random-forest-based, cascaded \r
regression model for face alignment by using a novel locally lightweight \r
feature, namely intimacy definition feature (IDF). This feature is more \r
discriminative than the pose-indexed feature, more efficient than the histogram \r
of oriented gradients (HOG) feature and the scale-invariant feature transform \r
(SIFT) feature, and more compact than the local binary feature (LBF). \r
Experimental validation of the algorithm shows that it achieves state-of-the-art \r
performance when testing on some challenging datasets. Compared with the \r
LBF-based algorithm, the method achieves about twice the speed, 20% improvement \r
in terms of alignment accuracy, and save an order of magnitude on memory \r
requirement.
