Abstract
Most of the action recognition researchers are undergoing intense study on sparse representation, due to its discriminative nature. The basis of the sparse representation is sparse coding, which give way for creating sparse dictionaries. The aim of this paper is to show the details about action recognition in video; the basics of sparse representation and its usage in action recognition; advancements in sparse representation; practical issues of recent sparse representation methods and future possibilities to solve such issues. This paper also provides various models and techniques used for the sparse representation based action recognition.
