Реферат: The invention relates to a method for assessing image quality between a reference image and an impaired image. The method comprises the steps of: - subband decomposition (120) of the luminance component of the reference image into N subbands, called reference subbands and of the luminance component of the impaired image into N subbands, called impaired subbands; - errors computation (150, 160) from the reference subbands and from the impaired subbands; and - pooling (170) the computed the errors. According to the invention, the subband decomposition is based on a wavelet transform adapted to decompose each of the luminance components into L levels of decomposition, with L a positive integer determined as a function of the image height and of the distance of visualization.
