Abstract

In this paper, we propose a new similarity measure for color images, that is angular distance of cumulative histogram. The measure is compared to previous popular measure that is cumulative L₁ distance measure on RGB and HSV color space. We show that our method produces a better result than cumulative L₁ distance measure. Moreover, to increase the accuracy, we introduce the weighting method. Weights are applied to the RGB similarity, D_R D_G, D_B, according to a Hue histogram of the query image. The weighting method increase accuracy and perceptually relevant result.
