Abstract: Various embodiments relate to a video coding system in which some elements required for decoding are generated according to a process that not specified within the video coding system. This process is hereafter referenced to as being the “external” process. This external process may generate “external” reference pictures to be used by a decoder that is adapted to use these external pictures. Encoding method, decoding method, encoding apparatus, decoding apparatus based on this post-processing method are proposed.

Abstract: A method and system are provided for processing image content. The method comprises receiving information about a content image captured at least by one camera. The content includes multi-view representation of an image including both distorted and undistorted areas. The camera parameters and image parameters are then obtained and used to determine to which areas are undistorted and which areas are distorted in said image. This is used to calculate depth map of the image using the determined undistorted and distorted information. A final stereoscopic image is then rendered that uses the distorted and undistorted areas and calculation of depth map.

Abstract: An apparatus and a method are provided for image processing. In one embodiment, the method comprises accessing a plurality of images captured by at least a reference camera, wherein the images represent a plurality of views corresponding to said same scene. A plurality of plane sweep volume (PSV) slices are then generated from said images and computing for each slice a flow map from at least the reference camera calibration parameter and this flow map a previous slice of the plane sweep volume is generated.

Abstract: The present disclosure relates to the transmission of sets of data and metadata and more particularly to the transmission of light-field contents. Light-field data take up large amounts of storage space which makes storage cumbersome and processing less efficient. In addition, light-field acquisition devices are extremely heterogeneous and each camera has its own proprietary file format. Since acquired light-field data from different cameras have a diversity of formats a complex processing is induced on the receiver side. To this end, it is proposed a method for encoding a signal representative of a light-field content in which the parameters representing the rays of light sensed by the different pixels of the sensor are mapped on the sensor. A second set of encoded parameters are used to reconstruct the light-field content from the parameters representing the rays of light sensed by the different pixels of the sensor.

Abstract: A method is proposed for detecting occlusions in an image captured by a light field capturing system, comprising, for at least one reference image belonging to a matrix of images captured by the light field capturing system: —calculating a depth map and a visibility map for pixels in the reference image; —determining at least one candidate area in the reference image in which the potential occlusion may occur based at least on a segmentation of the depth map; —determining an information representative of an occlusion state in the at least one candidate area based at least on visibility values of the visibility map associated with at least two neighborhoods of the at least one candidate area.
