3D face and motion estimation from sparse points using adaptive bracketed minimization
This paper presents a novel method for estimating camera motion and reconstructing human face from a video sequence. The coarse-to-fine method is applied via combining the concepts of Powell's minimization with gradient descent. Sparse points defining the human face in every frame are tracked u...
