Directional Analytic Discrete Cosine Frames

Directional Analytic Discrete Cosine Frames

Block frames called <italic>directional analytic discrete cosine frames</italic> (DADCFs) are proposed for sparse image representation. In contrast to conventional overlapped frames, the proposed DADCFs require a reduced amount of 1) computational complexity, 2) memory usage, and 3) glob...
