| Abstract: | This study presents a novel dictionary pruning algorithm that found
dictionaries of optimized size for a given dataset, without compromising its
approximation accuracy and performance. It is achieved by applying KSVD
(K-means singular value decomposition) algorithm
to patches of
dictionary. Proposed method optimized dictionary selection, and with KSVD
yielded better video denoising than KSVD with fixed dictionary. |
