An Approach of Image Feature Point Extraction Based on Wavelet Multiscale Analysis
Ning He · Microcomputer Development · 2003
Content-based image retrieval becomes a hot research topic due to the rapid increase of out of order image data. In order to solve the problem of lacking the spatial knowledge of common color features, presented an approach based on feature points for the content-based image retrieval. Meanwhile, the technology of relevance feedback was combined with the algorithm presented in the paper to enhance the effectiveness of retrieval. The comparison of the retrieval results to that of other systems shows that the approach proposed in the paper is effective.
