Coarse-to-Fine Adaptive People Detection for Video Sequences by Maximizing Mutual Information

open access: yesSensors, 2018
Applying people detectors to unseen data is challenging since patterns distributions, such as viewpoints, motion, poses, backgrounds, occlusions and people sizes, may significantly differ from the ones of the training dataset. In this paper, we propose a
