In this paper, a discriminative two-phase dictionary learning framework is proposed for classifying human action by sparse shape representations, in which the first-phase dictionary is learned on the selected ...
We propose a "zeroth class" trick for detecting undiscriminating frames of the test video and eliminating them before voting on the action categories. ...
Sect.3 presents the zeroth class dictionary learning framework for human action recognition. ...
