1. A method comprising:
decoding one or more patches that fail to include parent patch information identifying a respective patch from which the one or more patches were generated;
for a pixel of a plurality of pixels of a sub patch that includes the parent patch information and sub patch location information that identifies a location of the sub patch in relation to the respective patch from which the sub patch was generated, comparing depth values of the pixel of the sub patch and a corresponding pixel of the respective patch from which the sub patch was generated to determine a difference therebetween;
in an instance in which the difference satisfies a predefined threshold indicative of a variation therebetween, decoding the pixel of the sub patch; and
in an instance in which the difference fails to satisfy the predefined threshold, discarding the pixel of the sub patch without decoding.
