An adaptive coding scheme, based on a modification of the discrete cosine transformation, is used to encode image signals. The coding performance is compared with those of the DCT and the Walsh-Hadamard transform. The proposed coding scheme is simpler than the DCT, but its performance is quite close to that of the DCT. The adaptivity in our coder is achieved by using a suitable classification method and distributing the available channel capacity to different classes according to their energy level.<>
