View-aware Salient Object Detection for 360° Omnidirectional Image

no code implementations27 Sep 2022 Junjie Wu, Changqun Xia, Tianshu Yu, Jia Li

Inspired by humans' observing process, we propose a view-aware salient object detection method based on a Sample Adaptive View Transformer (SAVT) module with two sub-modules to mitigate these issues.

Salient Object Detection with Purificatory Mechanism and Structural Similarity Loss

1 code implementation18 Dec 2019 Jia Li, Jinming Su, Changqun Xia, Mingcan Ma, Yonghong Tian

Through these two attentions, we use the Purificatory Mechanism to impose strict weights with different regions of the whole salient objects and purify results from hard-to-distinguish regions, thus accurately predicting the locations and details of salient objects.

Distortion-adaptive Salient Object Detection in 360$^\circ$ Omnidirectional Images

no code implementations11 Sep 2019 Jia Li, Jinming Su, Changqun Xia, Yonghong Tian

Moreover, benchmarking results of the proposed baseline approach and other methods on 360$^\circ$ SOD dataset show the proposed dataset is very challenging, which also validate the usefulness of the proposed dataset and approach to boost the development of SOD on 360$^\circ$ omnidirectional scenes.

Selectivity or Invariance: Boundary-aware Salient Object Detection

no code implementations ICCV 2019 Jinming Su, Jia Li, Yu Zhang, Changqun Xia, Yonghong Tian

In this network, the feature selectivity at boundaries is enhanced by incorporating a boundary localization stream, while the feature invariance at interiors is guaranteed with a complex interior perception stream.
