摘要： Stereoscopic image processing methods and apparatus are described. Left and right eye images of a stereoscopic frame are examined to determine if one or more difference reduction operations designed to reduce the luminance and/or chrominance differences between the left and right frames is within a range used to trigger a difference reduction operation. A difference reduction operation may involve assigning portions of the left and right frames to different depth regions and/or other region categories. A decision on whether or not to perform a difference reduction operation is then performed on a per regions basis with at the difference between the left and right eye portions of at least one region being reduced when a difference reduction operation is to be performed. The difference reduction process may, and in some embodiments is, performed in a precoder which processes left and right eye images of stereoscopic frames prior to stereoscopic encoding.

摘要： Methods and apparatus relating to encoding and decoding stereoscopic (3D) image data, e.g., left and right eye images, are described. Various pre-encoding and post-decoding operations are described in conjunction with difference based encoding and decoding techniques. In some embodiments left and right eye image data is subject to scaling, transform operation(s) and cropping prior to encoding. In addition, in some embodiments decoded left and right eye image data is subject to scaling, transform operations(s) and cropping prior to being output to a display device. Transform information, scaling information and/or cropping information may be included in a bitstream communicating encoded left and right eye images. The amount of scaling can be the same for an entire scene and/or program.

摘要： Methods and apparatus for stereoscopic image encoding and decoding are described. Left and right eye images are encoded following an entropy reduction operation being applied to one of the eye images when there is a difference between the left and right images of an image pair. Information about regions of negative parallax within the entropy reduced image of an image pair is encoded along with the images. Upon decoding a sharpening filter is applied to the image in an image pair which was subjected to the entropy reduction operation. In addition edge enhancement filtering is performed on the regions of the recovered entropy reduced image which are identified in the encoded image data as regions of negative parallax. Interleaving of left and right eye images at the input of the encoder combined with entropy reduction allows for efficient encoding, storage, and transmission of 3D images.

摘要： Methods and apparatus for performing stereoscopic image encoding and decoding are described. Left and right eye images are generated. Image difference information is generated, e.g., a set of pixel values resulting from XORing the pixel values of the left and right eye images. One of the left and right eye images is compressed along with the difference map. The compressed image and compressed difference map is stored and/or transmitted. Stereoscopic images are generated by decompressing and using the received compressed image and compressed difference information. Prior to generation of the difference map the left and right eye images may be subject to a transposition operation to minimize the differences between the images and thus the size of the difference map. When transposition is applied, transposition information is stored and communicated in addition to the compressed image data so that the transposition can be reversed during the stereoscopic image generation process.
