Finding sparse representation of quantized frame coefficients using 0-1 integer programming

The use of overcomplete dictionaries, or frames, has received increased attention in low-bit-rate compression. Several vector selection algorithms, such as Matching Pursuit, Orthogonal Matching Pursuit and FOCUSS have been developed to get sparse representations of signals. In these algorithms, cont...
