Abstract

In Itti's model, which was one of the representative saliency models proposed in 1998, a Gaussian pyramid is used to analyze color information in scene images, and to generate a color conspicuity map. In this conspicuity map, some important objects can be located by salient areas, but their contours cannot be described clearly and perfectly. In this work, a wavelet low-pass pyramid is used to generate a color conspicuity map, and the contours of important objects pop out perfectly from salient areas. Experimental results validate the superiority of the proposed method.
