Abstract
A new family of orthogonal transform called dyadic transform (DT) is proposed for image compression by using the principle of dyadic symmetry. Two order-8 DTs are generated and their implementation is very simple in that it only requires operations of addition and binary shift. Performance evaluations using a statistical model and real images show that the performance of the proposed transforms is very close to that of DCT
