Abstract :
In fractal image compression, the mean squared error (MSE) computations of the eight orientations of the domain blocks can be reduced into two groups of inner products in the frequency domain. A very simple classification scheme is presented for reducing the two groups of computations into one, which makes the encoder up to 4.7 times faster
