Transform based spatio-temporal descriptors for human action recognition

Classic transformation methods have been widely and efficiently used in image processing areas, such as image de-noising, image segmentation, feature detection, and compression. Based on their compact signal and image representation ability, we apply the transform based techniques on the video recognition area to extract discriminative information from each given video sequence, and use the transformed coefficients as methods on theKTHand theHollywooddatasets,whichhave been extensively studiedbya lot of researchers. The proposed descriptors, especially the wavelet transform based descriptor, yield promising results on
