Further, the method may include determining a plurality of closest pixels, determining a value for each of the plurality of closest pixels, and determining a distance between the missing pixel and each of the plurality of closest pixels. The method may also include classifying each of the plurality of closest pixels as either an edge-pixel or a non-edge pixel and determining a value of the missing pixel at least partially based on the value of each of the plurality of closest pixels, the distance between the missing pixel and each of the plurality of closest pixels, and a classification of each of the plurality of closest pixels.

    摘要: 3D image data can be modified based on user preference data received from a user. The user preference data may be received at a first device and used to adjust 3D image data generated by the first device for presentation by a display device, or the first device may receive the user preference data and transmit it to a display device such that the display device may adjust the 3D image data based on the user preference data. The 3D image data may be adjusted based on user preference data to support presentation of 3D imagery on the display device in a manner desired by a user. 3D user viewing preferences may include an amount of pop-out effect in images, a stereo baseline of images, a depth range of images, a spatial distribution of images, a degree of depth sharpness in images, or specification of a user's dominant eye.

    摘要: In general, techniques are described for determining a vision-based quality metric for three-dimensional (3D) video. A device (12, 14) comprising a 3D analysis unit (24, 48) may implement these techniques to compute a 3D objective metric (36, 60). The 3D analysis unit (24, 48) estimates an ideal depth map (62, 70) that would generate a distortion limited image view using DIBR-based 3D video data (34) and then derives one or more distortion metrics (64, 72) based on quantitative comparison of the ideal depth map (62, 70) and a depth map (28, 58) used in the generation of the DIBR-based 3D video data (34). Based on the derived one or more distortion metrics (64, 72), the 3D analysis unit (24, 48) computes the objective metric (36, 60) to quantify visual quality of DIBR-based video data (34). The 3D objective metric (36, 60) may be used to alter or otherwise adjust depth estimation and encoding/decoding parameters to correct for expected visual discomfort.

    摘要: In general, techniques are described for transforming video data in accordance with human visual system feedback metrics. For example, an apparatus comprising a transformation module, a parameter discovery module and a human visual system (HVS) feedback module implements these techniques. The parameter discovery module configures the transformation module to generate three-dimensional (3D) video data in accordance with parameters defining capabilities supported by a 3D display device. The transformation module transforms video data to generate the 3D video data. The HVS feedback module determines, while the transformation module transforms the video data, one or more metrics using an HVS model that reflects a quality of 3D visualization of the generated 3D video data with respect to a human visual system and reconfigures the one or more modules based on the determined one or more metrics to refine the generation of the 3D video data.
