Sketch-based image retrieval by using saliency

Abstract

A method of sketch-based image retrieval by using saliency is proposed. This paper introduces saliency based on the color contrast into the sketch-based image retrieval to solve the common problems of scale and translation. Moreover, an improved Hausdorff distance is proposed to increase punishment on outliers, which avoids the negative effects caused by the outliers. The experiment result shows that the proposed method has better performance in retrieval accuracy than HD-MHD and TLS-HD.
