Codage hybride adaptatif d'images en vue de la transmission à bas débit : logiciel et matériel

Abstract : Image coding methods are used for low rate transmission. The difference between these methods lies in compression ratio and image subjective quality. We developed a new image coding method based on a visual classifier. A visual vector quantization is applied on the discret cosine transform coefficients, using the correspondance between the image domain and transform domain. A parallel coding system is described here. It's based on digital signal processors and transputers
