Abstract:
A depth map aligning method and a system are provided. The depth map aligning method includes the following steps. A view warping is performed to a left-view image and a right-view image of a real-view image according to a corresponding depth map to obtain a right-virtual view image, a left hole information, and a right hole information thereof. A residual difference of pixel, which is not a hole, is obtained by pixel to pixel. If the residual difference of the pixel is larger than a first threshold value, a reverse warping is performed to obtain a coordinate of the pixel. The depth value of the pixel is aligned according to the depth value of one or more pixels in a vicinity of the obtained coordinate.
Abstract:
A method and system for encoding three-dimensional (3D) video are provided. The method includes: obtaining a depth map of the 3D video, wherein the depth map includes multiple pixels and each of the pixels has a depth value; identifying a first contour of an object in the depth map; changing the depth values according to whether the pixels are located on the first contour to generate a contour bit map; compressing the contour bit map to generate a first bit stream, and decompressing the first bit stream to generate a reconstructed contour bit map; obtaining multiple sampling pixels of the pixels in the object according to a second contour corresponding to the object in the reconstructed contour bit map; and, encoding locations and the depth values of the sampling pixels. Therefore, a compression ratio of the 3D video is increased.

A method for storing interpolation data is provided, which includes the following steps: dividing a buffer into a plurality of regions, and using the regions to store the interpolation data of a plurality of non-integer points. The decimal part of each logical coordinate for each of the non-integer points is identical to that of the corresponding logical coordinate for another of the non-integer points in the same region.
