摘要： A synthetic image block in a synthetic picture is generated for a viewpoint based on a texture image and a depth image. A subset of samples from the texture image are warped to the synthetic image block. Disoccluded samples are marked, and the disoccluded samples in the synthetic image block are filled based on samples in a constrained area. The method and system enables both picture level and block level processing for synthetic reference picture generation. The method can be used for power limited devices, and can also refine the synthetic reference picture quality at a block level to achieve coding gains.

摘要： A method interpolates and filters a depth image with reduced resolution to recover a high resolution depth image using edge information, wherein each depth image includes an array of pixels at locations and wherein each pixel has a depth. The reduced depth image is first up-sampled, interpolating the missing positions by repeating the nearest-neighboring depth value. Next, a moving window is applied to the pixels in the up-sampled depth image. The window covers a set of pixels centred at each pixel. The pixels covered by the window are selected according to their relative position to the edge, and only pixels that are within the same side of the edge of the centre pixel are used for the filtering procedure. A single representative depth from the set of selected pixel in the window is assigned to the pixel to produce a processed depth image.
摘要翻译：一种方法以降低的分辨率对深度图像进行内插和滤波，以使用边缘信息恢复高分辨率深度图像，其中每个深度图像包括位置处的像素阵列，并且其中每个像素具有深度。缩小的深度图像首先被上采样，通过重复最近相邻的深度值来插值缺失的位置。接下来，将运动窗口应用于上采样深度图像中的像素。窗口覆盖以每个像素为中心的一组像素。由窗口覆盖的像素根据其与边缘的相对位置来选择，并且仅将中心像素的边缘的同一侧内的像素用于滤波过程。将来自窗口中的所选像素的集合的单个代表深度分配给像素以产生经处理的深度图像。
