A Cuboid Bi-Level Log Operator for Action Classification
We propose a 3-D cuboid bi-level Laplacian-of-Gaussian (CBLoG) operator with high speed and invariant space-time scale for detecting abrupt changes of signals in videos. This 3-D CBLoG operator is applied in the detection of spatio-temporal interest points in videos. Then, we extract rich feature de...
