A Wavelet-based Image Retrieval System An ECE 278A Project Report by

Abstract

In this report, we propose a wavelet-based content descriptor with which we implement an image retrieval system. Initially, we propose the wavelet-based weighted standard deviation texture descriptor. We then show how to extend this descriptor to characterize both texture and color in images. Thus, we obtain a compact feature vector that characterizes images in terms of both texture and color. We use this feature vector to implement an image retrieval system, using the weighted L1 distance measure.
