Title (EN) IMAGE PROCESSING METHOD AND IMAGE PROCESSING APPARATUS USING LEAST SIGNIFICANT BITS
(FR) PROCÉDÉ DE TRAITEMENT D'IMAGE ET APPAREIL DE TRAITEMENT D'IMAGE UTILISANT DES BITS DE POIDS FAIBLE
Abstract: front page image
(EN)Provided are an image processing method and image processing apparatus using least significant bits (LSBs). The image processing method includes generating first binary codes by converting pixel values of an input image into a binary code format; converting the first binary codes into gray codes and determining a predetermined number of sequential LSBs from among the gray codes; and generating second binary codes by converting the determined LSBs of the gray codes into the binary code format.
(FR)L’invention concerne un procédé de traitement d'image et un appareil de traitement d'image utilisant des bits de poids faible (LSB). Le procédé de traitement d'image consiste à générer de premiers codes binaires par conversion de valeurs de pixels d'une image d'entrée en un format de code binaire; à convertir les premiers codes binaires en codes de Gray et déterminer parmi les codes de Gray un nombre préétabli de LSB séquentiels; et à générer de seconds codes binaires par conversion des LSB déterminés des codes de Gray dans le format de code binaire.
