Semantic Pooling for Complex Event Analysis in Untrimmed Videos.
IEEE Transactions on Pattern Analysis and Machine Intelligence(2017)
摘要
Pooling plays an important role in generating a discriminative video representation. In this paper, we propose a new semantic pooling approach for challenging event analysis tasks (e.g., event detection, recognition, and recounting) in long untrimmed Internet videos, especially when only a few shots/segments are relevant to the event of interest while many other shots are irrelevant or even mislea...
