Abstract
A method is provided in one example embodiment that includes receiving a plurality of depth values corresponding to pixels of an image; and filtering the image as a function of a plurality of variations in the depth values between adjacent pixels of a window associated with the image. In more detailed embodiments, the method may include encoding the image into a bit stream for transmission over a network. The filtering can account for a bit rate associated with the encoding of the image.
Claims20
A method, comprising:
- receiving a plurality of depth values corresponding to pixels of an image;
- and
- filtering the image as a function of a plurality of variations in the depth values between adjacent pixels of a window associated with the image.
Logic encoded in one or more non-transitory media that includes code for execution and when executed by one or more processors is operable to perform operations comprising:
- receiving a plurality of depth values corresponding to pixels of an image;
- and
- filtering the image as a function of a plurality of variations in the depth values between adjacent pixels of a window associated with the image.
An apparatus, comprising:
- one or more processors;
- a memory;
- and
- a video encoder with a depth-guided filter, wherein the apparatus is configured for:
- receiving a plurality of depth values corresponding to pixels of an image;
- and
- filtering the image as a function of a plurality of variations in the depth values between adjacent pixels of a window associated with the image.
