Subband Coding of images, which can be seen as an extension of orthogonal transformations, has been introduced by Woods and O’Neil [8]. In [8], the subbands are further encoded by DPCM. In this study, it is proposed to use subband coding as a stand alone coding technique. The emphasis is put on the question of subband quantization. A methology is proposed where the quantization step of the subbands is taken so as to minimize a quantization noise power weighted by a sensitivity function of the eye.
