Human face can exhibits complex and strong changes that are both unpredictable and varying in time Now a days, facial expression recognition has become a emerging and research topic due to ad-vancement in this field. To overcome the disadvantages of conventional group-wise registration methods Spatio-temporal information and SOM algorithm used in recognition stage.This paper presents sparse representation with sparsity estimation and variable step size to improve recognition efficiency and accuracy. We have adopted SOM algorithm for better performance with reference to sparse representation classification algorithm. We also explored Sparsity Orthogonal matching algorithm is used in atlas construction to reach to true sparsity and lead to improved sparse representation as well as to resolve sparse coefficient and larger step size to shorten the time of iterations. The recognition rate is higher than other method shows by experimental result.
