The present invention pertains to a method for selecting a version of a document. The user inputs an identifier of a document at the level of his receiver connected to at least one communication network, and initiates a search request to receive versions of at least one part of this document. The receiver then receives a plurality of versions of the said document. Each version received is analysed by a plurality of evaluation modules so as to calculate an evaluation value for each version received according to a predetermined criterion. The receiver selects for each of the evaluation modules a version of the document having the best evaluation in respect of this criterion, and displays the identifiers of versions having the best evaluations according to each criterion. The user can then easily select the version for reproduction thereof which best meets a criterion. The invention also relates to a receiver implementing the said method.

A method for assessing the quality of a distorted version of a frame sequence includes the steps of determining a last spatial distortion by comparing a block of a last frame (I) of the sequence with a corresponding block of the distorted version of the last frame, determining, in a last-but-one frame, a best-matching block matching said block of the last frame best, determining a last-but-one spatial distortion by comparing the determined best-matching block of the last-but-one frame with a corresponding block of the distorted version of the last-but-one frame, determining a spatio-temporal perceptual distortion value associated with said block using said determined distortions and using the determined spatio-temporal perceptual distortion value for assessing the quality.

The present invention relates to a method for image processing to generate, from a source image having a predefined width to height ratio, called initial ratio, and an information banner having predefined width to height ratio, called banner ratio, a final image having a width called final and a height called final and for which the width to height ratio, called final ratio, is different from the initial ratio, comprising the following steps:

Method for image format conversion with insertion of an information banner

A method for assessing image quality between a reference image and an impaired image is disclosed. The method comprises the steps of 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.
