Salient locations search based on human visual attention: An experimental analysis

Abstract

To explore whether the conscious options or eye movements of human beings are influenced by bottom-up saliency, both theoretical and experimental analysis are presented in this paper. In the first experiment, the subjects are required to indicate most interesting regions of test pictures in the scene. In the second experiment, the subjects are required to look around test pictures in the scene. Then, the bottom-up saliency values of test pictures are computed by Itti model of that is one well-known visual attention. It is indicated that the interest points and fixation locations are correlated with the bottom-up saliency locations. Thus we propose two methods to study on visual attention that can be used to predict which areas of the images will draw subjects' visual attention: fixation location predictions and interest point predictions.
