    • An image encoding method in which when transmitting or storing an image, a frame of the image is divided into predetermined-sized processing regions, and for each processing region, a pixel value of each pixel is predicted for the encoding. The method includes a step that determines one pixel value, which is assigned to and represents each object in the processing region, to be an object pixel value that is associated with an object identifier for identifying the relevant object; a step that generates, based on each object pixel value and the pixel value of each pixel in the processing region, an object map that indicates which object has been obtained at each pixel in the processing region, by using the object identifier; a step that generates a predicted image for the processing region by assigning the object pixel value to each pixel in accordance with the object map; a step that encodes the object map; a step that encodes each object pixel value; and a step that performs predictive encoding of an image signal for the processing region by using the predicted image.

    • The present invention relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of encoding and decoding multi-viewpoint images in accordance with a mode that is compatible with an existing mode.
      A compatible encoder generates a compatible stream by encoding an image A 1 that is a compatible image in units of access units. An auxiliary encoder generates an encoded stream of a multiplexed image of auxiliary images by encoding a multiplexed image of images B1 and C 1 that are auxiliary images used when multi-viewpoint images are generated from the compatible image in units of access units. A multiplexing unit transmits the compatible stream, a 3DV Representation Delimiter representing a boundary of a unit, and an encoded stream of the multiplexed image of the auxiliary images. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.

    • A method and system are described for preparing a batch 15 of data sets 1-11 for a batch processing using a predetermined correlation encoding operation. In a first step, the batch 15 of data sets 1-15 is analysed to determine a plurality of correlation parameters 22 representing degrees of correlation between member data sets 1-11 of said batch 15 of data sets 1-11. In a second step, the correlation parameters 22 are used to generate an optimized correlation dependency graph 16 of the member sets 1-11 for performing the predetermined correlation encoding operation. By optimizing the correlation dependencies between data sets for subsequent processing, e.g. data compression, of the data sets, the advantages of correlation encoding can be used, even for data sets which appear a priori to be unordered and only weakly correlated.
