A Bayesian Model Saliency Detection Algorithm Based on Background Information Evaluation

Abstract

Abstract: Aiming at the influence of complex background information on salient object detection in natural images, this paper proposes a saliency detection method based on background information prediction and Bayesian model selection optimization. First, in order to extract complete prior information, a prior saliency map is generated according to the evaluation of the connectivity between the background information and the image boundary, and whether the image boundary is the background. Secondly, in order to reduce the interference of background information, corner detection is performed on saliency map generated by popular sorting algorithm, and the more accurate salieney points are selected to construct convex hull. Finally, Bayesian model is used for selection optimization to suppress the background information with the same characteristics as the salient object. Experiment is tested on two public datasets and compared with four classical saliency detection algorithms. The results show that the proposed algorithm can improve the accuracy of saliency detection and regional integrity.
