    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 optimise 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: The invention relates to the encoding of visual data captured by two or more cameras in a layered depth format.The invention proposes a method and device for layered s depth image encoding. The device is adapted for encoding at least one occlusion layer of the layered depth image with a greater horizontal width than a foreground layer of the layered depth image. The method comprises a corresponding step. Further, a non-transitory storage medium carrying at least one encoded layered depth image is proposed.The additional horizontal width can be used for conveying the part of information which is provided in the images/videos captured by the at least two cameras but not comprised in the foreground layer.

    摘要: The method implements an update step which is a selection among at least the following coding modes: a default coding mode which doesn't use the motion compensation for the calculation of the pixel if the pixel is not connected or which performs a low pass motion compensated temporal filtering of picture H of same level if the pixel is connected, an update_MV coding mode which performs a low pass motion compensated temporal filtering of picture H of same level according to a default motion vector calculated by taking into account motion vectors belonging to regions or pixels in the vicinity of the pixel to be calculated. Applications relate to video compression for transmission or storage of data.
