Abstract: In this paper, we propose a class of new orthogonal transforms: generalized parametric P-ordered slant transforms by using the idea of parameterization and mutation. We discuss the fast implementation of these transforms. On the basis, we compare them with other orthogonal transforms in the application of image compression. We show that the generalized parametric P-ordered slant transforms have a better tradeoff between the computational complexity and their compression effects.
