CBIR, illumination invariants, MRF

Content-based image retrieval (CBIR) systems target database images using feature similarities with respect to the query. Our CBIR demonstration utilises novel illumination invariant features, which are extracted from Markov random field (MRF) based texture representations. These features allow retrieving images with similar scenes comprising colour-textured objects viewed with different illumination brightness, spectrum or direction. The illumination invariant retrieval is verified on textures from the Outex and CUReT textures databases.
