Information Bottleneck Approach to Spatial Attention Learning

Qiuxia Lai, Yu Li, Ailing Zeng, Minhao Liu, Hanqiu Sun, Qiang Xu

IJCAI 2021poster

The selective visual attention mechanism in the human visual system (HVS) restricts the amount of information to reach visual awareness for perceiving natural scenes, allowing near real-time information processing with limited computational capacity. This kind of selectivity acts as an ‘Information…

Multi-contact frictional rigid dynamics using impulse decomposition

Sheng Li, Tianxiang Zhang, Guoping Wang, Hanqiu Sun, Dinesh Manocha

IROS 2017poster

We present an interactive and stable multi-contact dynamic simulation algorithm for rigid bodies. Our approach is based on fast frictional dynamics (FFD) [14], which is designed for large sets of non-convex rigid bodies. We use a new friction model that performs velocity-level multi-contact simulati…
