Implementation and Evaluation of a Content-Based Image Retrieval System
نویسنده
چکیده
CHROMA is a fully functional prototype content-based image retrieval system designed as part of the support mechanism for a digital photographic library. The paper outlines CHROMA's colour based indexing scheme and the access system which combines a Thumbnail Viewer, index structure Navigation Tool, a Sketch Tool and Query-by-Image-Example tool. Some recent results of evaluations of the effectiveness and usability of CHROMA and the methodology behind them are then reviewed. Although the evaluations are limited in some ways they show that whether users are attempting to find a specific known image or an image like another one the combination of tools represented by CHROMA is effective and useful.

Content-based image retrieval (CBIR) has received considerable research interest in the recent years. The basic problem in CBIR is the semantic gap between the high-level image semantics and the low-level image features. Region-based image retrieval and learning from user interaction through relevance feedback are two main approaches to solving this problem. Recently, the research in integra...
