摘要： In an image processing method to display a stereoscopic image on a target screen, a disparity information (200) is associated with the stereoscopic image and is adapted for the display of the stereoscopic image on an original screen, the size of the original screen being different from the size of the target screen, the stereoscopic image comprising a first image (20) and a second image (21). In order to optimize the disparity of the stereoscopic image, the method comprises selecting a part of said first image according to at least one property associated with the first image; calculating a target disparity information associated with the selected part of the image according to the viewing conditions associated with the target screen and the original disparity information associated with the selected part of the first image.

摘要： A method for displaying a sequence of pictures is disclosed. The sequence of picture coded as a multilayer stream comprising a base layer representative of the pictures of the sequence at a first resolution and/or first quality and at least one enhancement layer representative of the sequence pictures at a second resolution and/or second quality. The method comprises the following steps: decode the base layer from a random access point of the base layer and at least up to the decoding of a random access point of the enhancement layer to reconstruct pictures of the base layer, display the reconstructed pictures of the base layer, decode the enhancement layer from the random access point of the enhancement layer to reconstruct pictures of the enhancement layer, and display the reconstructed pictures of the enhancement layer. The method further comprises a processing step of the pictures of the enhancement layer before their display in such a way that the variation of the image content and/or of its quality between the picture of the base layer corresponding to the time of the random access point of the enhancement layer and the pictures of the enhancement layer is gradual.

摘要： The invention relates to an automatic detection method in a source image, of at least one area called a layout area comprising at least one layout, such as a logo and/or a score. According to the invention, the layout areas of a source image are detected using the salience of source image pixels. The detection is carried out in specific areas of the source image saliency map, usually in the areas corresponding to the corners of the image or to the bands in the upper part and lower part of the image. In these areas, two points are sought having maximum salience values and distant by at least p points from each other. These two points corresponding to the beginning and end of a layout area. The window bounding these two points then corresponds to a layout area.

摘要： 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.
