| Popis: | The invention is a method for assessing image quality value of a distorted image with respect to a reference image. The method comprises the following steps: - computing (22, 23, 24), for each pixel of the distorted image, at least one quality level with respect to the reference image; - adding (25), for the distorted image, the quality levels associated to each pixel by weighting them by a weight depending on a perceptual interest of the pixel in order to get the image quality value, the weight being lower for a pixel of high perceptual interest. |
