A system that incorporates teachings of the exemplary embodiments may include, for example, means for generating a disparity map based on a depth map, means for determining accuracy of pixels in the depth map where the determining means identifies the pixels as either accurate or inaccurate based on a confidence map and the disparity map, and means for providing an adjusted depth map where the providing means adjusts inaccurate pixels of the depth map using a cost function associated with the inaccurate pixels. Other embodiments are disclosed.
Quantization Splitting Multiple Description Encoder,
May 17, 2011
An improved (N:K) multiple description binning encoder that employs binning yet permits recovery of the input signal when fewer than K of the descriptions are available. In creating the encoder, a first choice is made of the number of descriptions that the encoder is to create and the minimum number of descriptions below which full recovery of the input signal is not possible. A second choice is made as to the number of descriptions that are to be broken up, to form descriptions that have two portions each. Once the first choice is made, appropriate quantization and binning scheme are selected by employing conventional techniques, and in response to the second choice, the chosen number of descriptions are each quantization split into coarse and fine quantization arrangements.
