Consistency in quantized matching pursuit [PDF]
1996 IEEE International Conference on Acoustics, Speech, and Signal Processing Conference Proceedings, 2002 This paper explores the effects of coefficient quantization in applying the matching pursuit algorithm to source coding of vectors in R/sup N/. By considering the issue of consistency, we find that even though matching pursuit is designed to produce a linear combination to estimate a given source vector, optimal reconstruction in the presence of ...
