A device and a method of up-sampling low resolution depth data is described, in particular in the form of a range map or a disparity map of stereo content, comprising the following successive steps: up-scaling the low resolution depth data to the desired resolution using a nearest neighbour interpolation to receive an up-scaled disparity map, detecting the horizontal and vertical bounds of each pixel of a high resolution colour image based on intensity differences, wherein the low resolution depth data correspond to the high resolution colour image, combining the up-scaled disparity map and the detected vertical and horizontal bounds by applying an averaging filter among an arbitrary shaped region by the utilization of horizontal and vertical integral data of the up-scaled disparity map to receive a high resolution disparity map. |
