(FR) TRAITEMENT D'IMAGES DESTINÉ À RETENIR DE PETITES DIFFÉRENCES DE COULEUR / DE GRIS
Abstract: front page image
(EN)A method for encoding a monochrome or color image. The method includes receiving an image and adjusting the image based on a global uniform macro-type color space. The image is modified spatially based on a local uniform micro-type edge characteristic that includes a just-noticeable difference (JND), and the image is outputted.
