Video saliency detection is intended to interpret the human visual system by modeling and predicting while observing a dynamic scene. This method is currently widely used in a variety of devices, including surveillance cameras and Internet-of-Things sensors. Traditionally, each video contains a large amount of redundancies in consecutive frames, while the common practices concentrate on extending the range of input frames to resist the uncertainty of input images. In order to overcome this problem, we propose Self-Adapted Frame Selection (SAFS) module that removes redundant information and selects frames that are highly informative. Furthermore, the module has high robustness and extensive application dealing with complex video contents, such as fast moving scene and images from different scenes. Since predicting the saliency map across multiple scenes is challenging, we establish a set of benchmarking videos for the scene change scenario. Specifically, our method combined with TASED-NET achieves significant improvements on the DHF1K dataset as well as the scene change dataset.
