Abstract

Non-negative matrix factorization (NMF) is an efficient local feature extraction algorithm of natural images. To extract well features of natural images, some sparse variants of NMF, such as sparse NMF (SNMF), local NMF (LNMF), and NMF with sparseness constraints (NMFSC), have been explored. Here, used face images and palmprint images as test images, and considered different number of feature basis dimension, the validity of feature extraction using SNMF, LNMF and NMFSC is testified. Experimental results demonstrate that the level of feature extraction of LNMF is the best, and that of NMFSC is the worse, which also provides some guidance to use different NMF based algorithm in image processing task, and our task in this paper behave certain theory research meaning and application in practice.
