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 statistical model and real images show that the performance of the proposed transforms is very close to that of DCT.
