摘要： A method of obtaining a saliency map from a plurality of saliency maps created from different visual quantities. Initially the saliency maps are normalized based on a theoretical maximum of each visual quantity. An intra-competition step selects the main saliency areas in each saliency map. An inter-competition step is then performed based on a sum of the intra-map competition with an inter-map redundancy term that is a function of the product of the intra-map competitions and of the probability of a site appearing on the saliency maps.

摘要： A method for assessing image quality between a reference image and an impaired image is disclosed. The method comprises the steps of: subband decomposition 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 from the reference subbands and from the impaired subbands; and pooling 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.
