A biological vision inspired framework for machine perception of abutting grating illusory contours
Xiao Zhang, Kai-Fu Yang, Xian-Shi Zhang +3
Higher levels of machine intelligence demand alignment with human perception and cognition. Deep neural networks (DNN) dominated machine intelligence have demonstrated exceptional…
PESFormer: Boosting Macro- and Micro-expression Spotting with Direct Timestamp Encoding
Wang-Wang Yu, Kai-Fu Yang, Xiangrui Hu +3
The task of macro- and micro-expression spotting aims to precisely localize and categorize temporal expression instances within untrimmed videos. Given the sparse distribution and…
Weak Supervision with Arbitrary Single Frame for Micro- and Macro-expression Spotting
Wang-Wang Yu, Xian-Shi Zhang, Fu-Ya Luo +4
Frame-level micro- and macro-expression spotting methods require time-consuming frame-by-frame observation during annotation. Meanwhile, video-level spotting lacks sufficient infor…
Weakly-supervised Micro- and Macro-expression Spotting Based on Multi-level Consistency
Wang-Wang Yu, Kai-Fu Yang, Hong-Mei Yan +1
Most micro- and macro-expression spotting methods in untrimmed videos suffer from the burden of video-wise collection and frame-wise annotation. Weakly-supervised expression spotti…
