  • Publication number: 20140015923
    Abstract: Systems and methods may be provided embodying a novel approach to measuring degradation (or distortion) by analyzing disparity maps from original 3D video and reconstructed 3D video. The disparity maps may be derived using a stereo-matching algorithm exploiting 2-view stereo image disparity. An overall distortion measure may also be determined resulting from the weighted sum of plural measures of distortions, one of the plural distortion measures corresponding to a measure of disparity degradation, and another one corresponding to a measure of geometrical distortion. The measure (or overall distortion measure) is used during real-time encoding to effect various decisions, including mode decision in the coding of each corresponding stereo pair, and in rate control (including stereo pair quantization).

  • Publication number: 20140002594
    Abstract: A depth map image, unlike a texture view, has smooth regions without complex texture and abrupt changes of pixel value at the object edges. While conventional Inter-prediction skip mode is very efficient for coding texture views, it does not include any Intra-prediction capability, which can be very efficient for coding smooth regions. The hybrid prediction skip mode according to the presently claimed invention includes an Inter-prediction Skip mode coupled with various Intra-prediction modes. The selection of the prediction mode is made by computing a Side Match Distortion (SMD) for the prediction modes. Because no additional overhead indicator bit is required and that the bitstream syntax is not altered, high coding efficiency is maintained and the coding scheme for coding depth maps in accordance to the presently disclosed invention can be implemented easily as an extension to existing standards.

    Abstract: Depth image compression is described for example, to enable body-part centers of players of a game to be detected in real time from depth images or for other applications such as augmented reality, and human-computer interaction. In an embodiment, depth images which have associated body-part probabilities, are compressed using probability mass which is related to the depth of an image element and a probability of a body part for the image element. In various examples, compression of the depth images using probability mass enables body part center detection, by clustering output elements, to be speeded up. In some examples, the scale of the compression is selected according to a depth of a foreground region and in some cases different scales are used for different image regions. In some examples, certainties of the body-part centers are calculated using probability masses of clustered image elements.

  • Publication number: 20130050424
    Abstract: A multiview video decoding apparatus receives and decodes an encoded stream obtained as a result of encoding residual information, 2D images for N views, and depth images for N views, the residual information being the error between synthetic-view images generated using the 2D images for N views and the depth images for N views, and 2D images for (M?N) views at the view synthesis positions of the synthetic-view images. A view synthesizing apparatus generates the synthetic-view images by using the 2D images and depth images for N views decoded by the multiview video decoding apparatus. A residual information compensating apparatus adds the residual information into the generated synthetic-view images. The apparatus may be applied to a system that conducts view synthesis, for example.

  • Publication number: 20130044183
    Abstract: Disclosed are a distributed video encoding/decoding method and a distributed video encoding/decoding apparatus, which can improve loss resilience and the quality of service. The distributed video encoding method first involves checking the state of a channel, determining a channel coding rate and the size of video data to be transmitted based on the checked state of a channel, determining the number of motion prediction performance steps based on the determined size of video data to be transmitted, encoding the video data to be transmitted by performing motion predictions according to the determined number of motion prediction performance steps, and channel-coding the encoded video data according to the determined channel coding rate. Accordingly, it is possible to improve loss resilience, even without additionally occupying network resources, thereby being capable of reducing the probability of decoding failure.

  • Publication number: 20130021435
    Abstract: In performing stereoscopic view, a shift information memory stores, as a number of pixel lengths, an offset indicating how far in a right direction or a left direction to move coordinates of pixels to realize stereoscopic view. When realizing stereoscopic view, a plane shift engine moves the coordinates of image data in a graphics plane in the right direction or the left direction by the number of pixel lengths indicated by the offset. When a scale of video data targeted for stereoscopic view is changed by a basic graphics plane, a shift distance of pixel coordinates by the plane shift engine is based on a number of pixel lengths obtained by multiplying the offset by a changed scaling factor in the horizontal direction.

    Abstract: The reproduction apparatus includes a remote control receiver that receives an instruction for adjusting an offset amount between the left-eye image data and the right-eye image data, a video signal processor that adjusts an offset amount between the left-eye image data and the right-eye image data so as to be an offset amount based on the instruction, and a CPU that determines whether an absolute value of the offset amount adjusted by the video signal processor is not more than a limit value. When the CPU determines that the adjusted absolute value of the offset amount is more than the limit value, the video signal processor adjusts the offset amount between the left-eye image data and the right-eye image data so that the absolute value of the offset amount between the left-eye image data and the right-eye image data is not more than the limit value.

    Abstract: There is an encoding of three dimensional (3D) information. The encoding may include receiving a signal including frames in a 3D video sequence, receiving caption information to appear in a caption window associated with the frames, and/or receiving disparity information associated with the frames. The encoding may also include determining frame disparity maps based on the disparity information associated with the frames. The frame disparity maps may be determined by dividing a part of a frame into a plurality of grid cells. The grid cells may define a disparity measure associated with locations in a grid. The grid cells may form a caption window disparity map dividable into equivalent size portions including an equivalent amount of grid cells. The encoding may also include encoding the frames, the caption information and the frame disparity maps. There is also a decoding of the 3D information.

  • Publication number: 20120314027
    Abstract: Multiview videos are acquired by overlapping cameras. Side information is used to synthesize multiview videos. A reference picture list is maintained for current frames of the multiview videos, the reference picture indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video. Each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list with a skip mode and a direct mode, whereby the side information is inferred from the synthesized reference picture. In addition, the skip and merge modes for single view video coding are modified to support multiview video coding by generating a motion vector prediction list by also considering neighboring blocks that are associated with synthesized reference pictures.
