Title: METHOD AND DEVICE FOR ASSESSING THE VISUAL QUALITY OF AN IMAGE OR A SEQUENCE OF IMAGES USING OBJECTIVE INDICATORS, AND CORRESPONDING COMPUTER PROGRAM
Abstract:
The invention relates to a method for assessing the visual quality of a tested image or sequence of images, on the basis of measuring distortions by type of area, including the following steps, for an image or a video to be tested: cutting said tested image into a set of spatial areas or said tested sequence of images into a set of spatiotemporal areas; determining at least one piece of information representative of a local distortion for each of said areas; classifying each of said areas into a class, from among a set of predetermined classes, representative of a type of content of said area; generating a report including at least one piece of information representative of the visual quality for each of said predetermined classes present in said tested image or sequence of images, determined from said information representative of the distortion and of the type of content assigned to the corresponding area.
