Image indexing based on vector quantization

摘要

We propose the computation of the color palette of each image in isolation, using Vector Quantization methods. The image features are, thn, the color palette and the historgram of the color quantization of the image with this color palettre. We propose as a measure of similitude the weighted sum the increase of the database without the recomputation of the image features and wituout substantial loss of discriminative power.
