Hierarchical boundary feature alignment network for video salient object detection
Year: 2025
Type: article
Abstract: The deep learning based video salient object detection (VSOD) models have achieved great success in the past few years, however, these VSOD models still suffer from the following two problems: i) struggle in accurately predicting those pixels surrounding salient objects; ii) unaligned features of different scales lead to deviations in feature fusion . To tackle these problems, we propose a hierarchical boundary feature alignment network (HBFA). Specifically, the proposed HBFA consists of a temporal–spatial fusion module (TSM) and three decoding branches. TSM captures multi-scale spatiotemporal information. The two boundary feature branches are used to guide the whole network to pay more attention to the boundary of salient objects, while the feature alignment branch is capable of fusing the features from the internal and external branches while aligning features across different scales. Our extensive experiments show that the proposed method reaches a new state-of-the-art performance.
