A Deep Clustering via Automatic Feature Embedded Learning for Human Activity Recognition
IEEE Transactions on Circuits and Systems for Video Technology(2022)
摘要
Traditional clustering algorithms are widely used for building bag-of-words (BOW) models to aggregate spatio-temporal feature points extracted from a video for human activity recognition problems. Their performances are restricted by the computational complexity which limits the number of feature points being used. In contrast, deep clustering yields good clustering performance without the limit o...
