Abstract

In this work, a simple orthogonal transform called dyadic transform (DT) is developed for image coding systems based on the principle of dyadic symmetry. The new transform has very simple implementation structure that requires only operations of addition and binary shift. Evaluations using a statistical model and real images show that the performance of the proposed transform is close to that of DCT and is better than the high correlation transform (HCT) and low correlation transform (LCT).
