a new approach for image compression using normal matrices

in this paper, we present a method for image compression on the basis of eigenvalue decomposition of normal matrices. the proposed method is convenient and self-explanatory, requiring fewer and easier computations as compared to some existing methods. through the proposed technique, the image is transformed to the space of normal matrices. then, the properties of spectral decomposition are dealt with to obtain compressed images. experimental results are provided to illustrate the validity of the method.
