Fixation Prediction Based On Scene Contours
2019 IEEE SYMPOSIUM SERIES ON COMPUTATIONAL INTELLIGENCE (IEEE SSCI 2019)(2019)
Abstract
Previous works suggest that scene contours play important roles in guiding visual attention. In this study, a computational model is proposed to improve the performance in visual saliency prediction by integrating the low- and mid-level visual cues and evaluate the contribution of scene contours in guiding visual attention. Firstly, we define three kinds of Gestalt principles based on mid-level cues, including contour density, closure, and symmetry to characterize the potential salient regions. In addition, we employ the classical bottom-up methods to generate low-level saliency maps. Finally, the proposed method combines the low-level cues from natural images and the mid-level cues from the corresponding contours to improve the fixation prediction. Experimental results show that the contour-based midlevel cues can remarkably improve the performance of the bottomup models in fixation prediction.
