Rotation invariance is one of the most important characteristics in texture classification. This paper proposes an algorithm for rotation invariance texture classification. The algorithm estimates dominant orientation of an image based on Gabor filters firstly and then constructs a multivariate decision tree with square criterion. It is an accurate solution to rotation invariance of a
