Abstract
Histogram comparison is a popular technique for image and video indexing. The complexity of the histogram technique can be reduced by representing the histogram by its moments. In this paper, we propose several techniques to improve the performance of basic histogram/moment-based technique. First, we propose to use orthogonal Legendre moments. Being orthogonal, Legendre moments provide superior performance compared to regular moments at a similar complexity. Secondly, we propose to compare the histograms of wavelet coefficients, in addition to the baseline histogram technique. The directional information provided by the wavelet bands enhances the performance of the histogram-based indexing technique.
