Pissaro: Perceptual Colour and Texture Queries using
Stackable Mosaics,
In IEEE International Conference on Multimedia Computing and

Florence, Italy, June 7-11 1999.This paper introduces Pissaro (Perceptual Image Similarity And Retrieval Online), a web based image retrieval system designed for combining, evaluating and comparing Content Based Image Retrieval (CBIR) techniques. The need for a query interface which allows the user to understand both query and subsequent retrievals is identified and implemented together with a stackable mosaic approach to query design which gives the benefit of pre-calculated features whilst allowing the user to paint queries. Several colour and texture based feature extraction methods are evaluated for CBIR including a new Perceptual Colour Histogram. Finally, the suitability of the stackable mosaic approach is demonstrated using colour and texture query combinations.
