The present invention relates generally to images. More particularly, an embodiment of the present invention relates to the pixel group segmented quantization and de-quantization of the residual signal in layered coding of high dynamic range images. By assigning the pixels in the residual image to different pixel groups based on the pixel value of the corresponding pixel in the decoded base layer signal, and by applying pixel group quantizing functions to assigned pixels a more efficient coding can be achieved.

Predictive image encoding and decoding with pixel group based quantization

Stereoscopic video data and corresponding depth map data for stereoscopic and auto-stereoscopic displays are coded using a coded base layer and one or more coded enhancement layers. Given a 3D input picture and corresponding input depth map data, a side-by-side and a top-and-bottom picture are generated based on the input picture. Using an encoder, the side-by-side picture is coded to generate a coded base layer Using the encoder and a texture reference processing unit (RPU), the top-and-bottom picture is encoded to generate a first enhancement layer, wherein the first enhancement layer is coded based on the base layer stream, and using the encoder and a depth-map RPU, depth data for the side-by-side picture are encoded to generate a second enhancement layer, wherein the second enhancement layer is coded based on to the base layer. Alternative single, dual, and multi-layer depth map delivery systems are also presented.

Frame compatible depth map delivery formats for stereoscopic and auto-stereoscopic displays

Stereoscopic video data and corresponding depth map data for multi-view auto-stereoscopic displays are coded using a multiplexed asymmetric image frame that combines an image data partition and a depth map data partition, wherein the size of the image data partition is different than the size of the depth map data partition. The image data partition comprises one or more of the input views while the depth map partition comprises at least a portion of the depth map data rotated with respect to the orientation of the image data in the multiplexed output image frame.
