Testing dimension reduction methods for image retrieval

Moravec P., Snášel V.

Image Processing & Communications

2006

Vol. 11, no 2

51-61

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 several standpoints: the visual impact, quality of generated "eigenfaces", size of reduced matrices and retrieval performance.
