Face Indexing and Retrieval by Spatial Similarity
Tadmeri Narayan Vikram, Chidananda Gowda K., Guru D. S., Shalini R. Urs · 2008
In this paper a face indexing scheme based on spatial similarity is proposed. Spatial scattering of anatomically relevant dominant points on faces is preserved in the kd-tree index structure for efficient retrieval. The methodology is invariant to linear transformation and is robust for pose and expression variations. Experimentation on ORL face database has corroborated the retrieval effectiveness and time efficiency of the proposed methodology
