Claim Text:
1. A method for filtering a disparity map associated with one view of a stereoscopic image comprising at least one object partially covering a first zone, comprising: determining at least a second zone around the object, said second zone bordering said object and said first zone; identifying at least one pixel of said at least a second zone whose disparity value is considered erroneous when the disparity value is outside an interval whose boundaries correspond to disparity values associated with neighbouring pixels that are positioned immediately before and immediately after said at least one pixel, on either a horizontal line or a vertical line, said neighbouring pixels being pixels defining at least partially either the object or the first zone; correcting the disparity value of said at least one identified pixels by assignment of a new disparity value only as a function of disparity values of pixels defining at least partially the object, or only as a function of disparity values of the pixels defining at least partially the first zone; and performing one of (1) providing the one view of the stereoscopic image and the disparity map to a display device and (2) transmitting the one view of the stereoscopic image and the disparity map via a communication channel.
