Forward adaptive KLT coding
C.E. Davila · 2009
A framework for implementing the forward adaptive Karhunen-Loeve Transform (FAKLT) is described. Unlike backward adaptive methods, FAKLT computes transform coefficients using basis vectors derived from the most recent signal frame. As a result, it exhibits improved energy compaction compared to the backward adaptive KLT. The method encodes only the KLT coefficients and a small amount of side information, the KLT basis vectors (eigenvectors) are not encoded.
