In this paper we propose the estimation method for the image affine information. The first method is based on the eigenvalues and eigenvectors for the covariance matrix of the given image, The second method is based on the x-shearing, y-shearing and the scaling decomposition using the specific relationships of the central moments for the specific transformation matrix. In addition we estimate the rotation and the aspect ratio information using the central moments of the reference image and the sensed image. Through the experiment, the second method has better performance than the first method.
