Salient Object Detection Based on a Novel Combination Framework Using the Perceptual Matching and Subjective-Objective Mapping Technologies

Abstract

The integrity and fineness characterization of non-connected regions and contours is a major challenge for existing salient object detection. The key to address is how to make full use of the subjective and objective structural information obtained in different steps. Therefore, by simulating the human visual mechanism, this paper proposes a novel multi-decoder matching correction network and subjective structural loss. Specifically, the loss pays different attentions to the foreground, boundary, and background of ground truth map in a top-down structure. And the perceived saliency is mapped to the corresponding objective structure of the prediction map, which is extracted in a bottom-up manner. Thus, multi-level salient features can be effectively detected with the loss as constraint. And then, through the mapping of improved binary cross entropy loss, the differences between salient regions and objects are checked to pay attention to the error prone region to achieve excellent error sensitivity. Finally, through tracking the identifying feature horizontally and vertically, the subjective and objective interaction is maximized. Extensive experiments on five benchmark datasets demonstrate that compared with 12 state-of-the-art methods, the algorithm has higher recall and precision, less error and strong robustness and generalization ability, and can predict complete and refined saliency maps.
