Oriented structure of the occlusion distortion: is it reliable?IEEE Transactions on Pattern Analysis and Machine Intelligence - Tập 24 Số 9 - Trang 1286-1290 - 2002
Weichuan Yu, G. Sommer, S. Beauchemin, K. Daniilidis
In the energy spectrum of an occlusion sequence, the distortion term has the same orientation as the velocity of the occluding signal. Other works claimed that this oriented structure can be used to distinguish the occluding velocity from the occluded one. We argue that the orientation structure of the distortion cannot always work as a reliable feature due to the rapidly decreasing energy contrib...... hiện toàn bộ
