    • The invention concerns a method for texturing a mesh associated with a surface (1) representative of a scene captured in a plurality of images (110 to 150), wherein at least a mesh element (10) of said mesh is at least partially visible from at least two first images (110 to 140) of the plurality of images (110 to 150). As to reduce the amount of texture information associated to multi-views data representative of the scene, the method comprises: - for each first image (110 to 140), association of a first texture information with said mesh element (10), - projection of the first texture information in said at least two first images (110 to 140), - for each first texture information, estimation of an error information according to a comparison result between the projected first texture information and the texture information of said at least two first images (110 to 140), and - selection of one of the at least two first texture information according to said error information. The invention also concerns a corresponding computation unit.

    • The invention relates to a image processing method to display a stereoscopic image on a target screen, a disparity information (200) being associated with said stereoscopic image and being 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 optimise the disparity of the stereoscopic image, the method comprises the following steps: - selecting a part of said first image according to at least one property associated with the first image, - calculating a disparity budget associated with the target screen according to viewing conditions associated with the target screen, - calculating a target disparity information associated with the selected part of the image according to the disparity budget and an original disparity information associated with the selected part of the first image.

    • The invention proposes a method for generating and processing depth data associated with a mapping of first image data comprised in a first image onto second image data comprised in at least a second image. Said method comprising the steps of generating a control signal which depends on a first saliency value determined using the first image data, wherein said control signal further depends on at least a second saliency value determined using the second image data, generating depth data using said mapping and processing the depth data wherein generating and/or processing of depth data is dependent on said control signal. This allows for more accurate generation and/or processing of the depth data in regions which are visually attracting and thus more likely in the focus of a viewer's attention.
