Background frame based video coding achieves a remarkable compress performance for surveillance video coding. In this paper, an improved Advanced Motion Vector Prediction (AMVP) scheme for surveillance video coding is proposed to make Motion Vector Prediction (MVP) more accurate when prediction unit (PU) references background (BG)-frame. Considering the correlations among the spatial PUs, the p...

In S2 Fig., the second and third rows of firing rate maps in panel A are swapped and incorrectly labeled "arena frame" and "room frame" respectively. Instead, the second row should be labeled “room frame” and the third row should be labeled “arena frame”. Also, the spatial coherence numbers for the fourth row of firing rate maps in panel A were incorrectly duplicated from the first row. Please ...

Cognitive control is the ability to coordinate multiple streams of information to prevent confusion and select appropriate behavioral responses, especially when presented with competing alternatives. Despite its theoretical and clinical significance, the neural mechanisms of cognitive control are poorly understood. Using a two-frame place avoidance task and partial hippocampal inactivation, we ...

This paper presents an approach for human activity recognition by representing the frames of the video sequence with the distribution of local motion features and their spatiotemporal arrangements. In this approach, the local motion features used for the representation of a frame are integrated from the ones detected in this frame and its temporal neighbors. The features’ spatial arrangements a...
