A motion-based deep learning system that detects abnormal crowd motion by analysing optical flow sequences using a CNN + LSTM architecture with motion coherence metrics. Designed for surveillance ...

Abstract: Panoramic optical flow enables a comprehensive understanding of temporal dynamics across wide fields of view. However, severe distortions caused by sphere-toplane projections, such as the ...

Abstract: The sparse optical flow method is a fundamental task in computer vision. However, its reliance on the assumption of constant environmental brightness constrains its applicability in high ...
