- Abstract:
-
The effective extraction and efficient utilization of features are among the most challenging tasks in salient object detection. The common convolutional neural network (CNN) can hardly reach a fine trade-off between effective feature extraction and efficient utilization. This paper proposes a bidirectional message link convolutional neural network (BML-CNN) model, which can extract and fuse effective features for salient object detection. First, the attention mechanism is used to guide the feature extraction module to extract the effective entity features, select, and integrate the multi-level context information in a progressive way. Second, the high-level semantic information is merged with shallow-profile information by a bidirectional message link, which is composed of a skip connection structure and a messaging link with a gating function. Finally, the saliency map can be generated by multi-scale fusion strategy, and effective features are encoded on several layers. The qualitative and quantitative experiments on six benchmark datasets show that the BML-CNN reaches the state-of-the-art performance under different indexes.
