Dimension Reduction Methods for Image Retrieval
Pavel Moravec, Václav Snåšel · 2006
In this paper, we compare performance of several dimension reduction techniques, namely LSI, NMF, SDD and FastMap. The qualitative comparison is based on rank lists and evaluated on a collection of faces from the Olivetti Research Lab. We compare the quality of these methods from both the visual impact, quality of generated "eigenfaces" and retrieval performance
