... as the constrained projection approximation subspace tracking (CPAST) algorithm, guarantees the orthonormality of the estimated signal subspace basis at each iteration. Thus, the proposed algorithm ... as constrained projection approximation subspace tracking (CPAST). This algorithm avoids the orthonormalization step in each iteration. We will show that order...

In the proposed edge direction estimation, the diagonal directional edge is considered ... the edge direction on the Bayer pattern. In the conventional SSC -based methods, the smoothness of the Bayer color difference along an edge is examined, and the deriva...
