Abstract
The present disclosure is directed to a method and a device for dealiasing borders in a 3D interpolated view, the interpolated view comprising at least foreground pixels with foreground video in formation and background pixels with background video information. The method comprises the step of detecting, in an interpolated disparity map, associated to the 3D interpolated view, an aliased border between the foreground pixels with a foreground disparity value and the background pixels with a background disparity value, the aliased border delimiting an inner aliased contour formed by foreground pixels and an outer aliased contour formed by background pixel, the aliased border having the form of a stair line; determining a weighting/dealiasing coefficient for each pixel of the outer contour said coefficient corresponding to the part of the pixel area included in the virtual right triangle defined by the two sides of each stair line to the area of the pixel; calculating video information for each pixel of the outer contour in combining the background video information and the foreground video information in a proportion defined by the determined weighting/dealiasing coefficient and replacing video information for each pixel of the outer contour by the calculated video information.
