A method and an apparatus for encoding a picture are disclosed. For at least one block of a picture to encode, a block predictor is determined () for a decoded first component () of said at least one block, from a reconstructed region of a first component of said picture. At least one second component of said at least one block is then encoded () by predicting said at least one second component from a second component of said block predictor. Corresponding decoding method and apparatus are disclosed.

Method and apparatus for encoding and decoding at least one block of a picture based on components of the at least one block

A content stream comprising video and synchronized illumination data is based on a reference lighting setup from, for example, the site of the content creation. The content stream is received at a user location where the illumination data controls user lighting that is synchronized with the video data, so that when the video data is displayed the user's lighting is in synchronization with the video. In one embodiment, the illumination data is also synchronized with events of a game, so that a user playing games in a gaming environment will have his lighting synchronized with video and events of the game. In another embodiment, the content stream is embedded on a disk.

The present disclosure generally relates to a method for predicting at least one block of pixels of a view () belonging to a matrix of views () obtained from light-field data belong with a scene. According to present disclosure, the method is implemented by a processor and comprises for at least one pixel to predict of said block of pixels: &#x2014;from said matrix of views (), obtaining () at least one epipolar plane image (EPI) belong with said pixel to predict, &#x2014;among a set of unidirectional prediction modes, determining () at least one optimal unidirectional prediction mode from a set of previous reconstructed pixels neighboring said pixel to predict in said at least one epipolar plane image, &#x2014;extrapolating () a prediction value of said pixel to predict by using said at least one optimal unidirectional prediction mode.

A method for generating at least one image with a first dynamic range, from an image with a second dynamic range, which is lower than the first dynamic range is described. The method includes obtaining an epitome of the image with a first dynamic range, called a first epitome. Thereafter, the image with a first dynamic range is generated from the image with a second dynamic range and the first epitome.

Methods and devices for generating, encoding or decoding images with a first dynamic range, and corresponding computer program products and computer-readable medium

A method for encoding and decoding an image block, an encoder, and a decoder are provided. The method for encoding an image block comprises: determining a local dynamic range of the block; adaptively precision-extending pixel values of the block based on the local dynamic range of the block; and encoding the block with an adaptively extended precision. The method for decoding an image block comprises: determining a minimum pixel value of the block and an indicating value for indicating a precision extension factor according to precision extension information; decoding the block according to the indicating value; and de-extending precision of the decoded block based on the minimum pixel value of the block and the precision extension factor. The precision of the intermediate calculations may be improved without increasing an original intermediate bit depth used in intermediate calculations.

Method for encoding and decoding image block, encoder and decoder

A method for constructing an epitome from an image divided into non overlapping blocks is disclosed. The method comprises:
