abstract = "This work presents a novel approach for motion description in
videos using multiple band-pass filters which act as first order
derivative estimators. The filters response on each frame are
coded into individual histograms of gradients to reduce their
dimensionality. They are combined using orientation tensors. No
local features are extracted and no learning is performed, i.e.,
the descriptor depends uniquely on the input video. Motion
description can be enhanced even using multiple filters with
similar or overlapping frequency response. For the problem of
human action recognition using the KTH database, our descriptor
achieved the recognition rate of 93.3% using three Daubechies
filters, one extra filter designed to correlate them, two-fold
protocol and a SVM classifier. It is superior to most global
descriptor approaches and fairly comparable to the state-
of-the-art methods.",
