Patent ID: 8537200

Claim:
A method comprising: assigning initial depth values to pixels of a video unit based on motion associated with the pixels relative to corresponding pixels of a previous video unit of a video sequence; identifying whether the initial depth values satisfy a threshold; assigning adjusted depth values to one or more of the pixels of the video unit for which the initial depth values satisfy the threshold, wherein the adjusted depth values are based on color associated with the pixels; generating a depth map for the video unit, wherein the depth map comprises an initialized depth map, wherein the initialized depth map comprises the initial depth values for a first subset of the pixels and the adjusted depth values for a second subset of the pixels; determining whether the video unit corresponds to a scene change relative to the previous video unit; if the video unit does not correspond to the scene change relative to the previous video unit, determining whether the video unit represents a low level of motion relative to the previous video unit; and if the video unit does not represent the low level of motion, defining a final depth map based on weighted averages of the depth values of the initialized depth map for the video unit and depth values of a previous depth map for the previous video unit.
