For the high quality three-dimensional broadcasting, depth maps are important data. Although commercially available depth cameras capture highaccuracy depth maps in real time, their resolutions are much smaller than those of the corresponding color images due to technical limitations. In this paper, we propose the depth map up-sampling method using a high-resolution color image and a low-resolu...

This paper describes a spatio-temporal super-resolution method using depth maps for static scenes. In the proposed method, the depth maps are used as the parameters to determine the corresponding pixels in multiple input images by assuming that intrinsic and extrinsic camera parameters are known. Because the proposed method can determine the corresponding pixels in multiple images by a one-dime...

High-quality depth map generation is a key component of free-viewpoint video (FVV), because the virtual view-point images used for FVV are synthesized from real multi-view images and their depth maps. However, synthesized images do not guarantee good quality if the depth maps are inaccurate. Many studies have been conducted to develop methods for generating accurate depth maps. A semi-automatic...

A method for depth estimation in a 2D image using wavelet analysis has been implemented with less computation that converts two-dimensional images of limited depth of field (DOF) into depth estimation for 3D image construction. Each image is first transformed to YUV domain and the Y component of the image is further transformed to the wavelet domain for major object detection. According to our ...

A depth image-based rendering (DIBR) technique is one of the rendering processes of virtual views with a color image and the corresponding depth map. The most important issue of DIBR is that the virtual view has no information at newly exposed areas, so called disocclusion. The general solution is to smooth the depth map using a Gaussian smoothing filter before 3D warping. However, the filtered...

three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...

A novel multi-view stereo reconstruction method is presented. The algorithm is focused on accuracy and it is highly engineered with some parts taking advantage of the graphics processing unit. In addition, it is seamlessly integrated with the output of a structure and motion pipeline. In the first part of the algorithm a depth map is extracted independently for each image. The final depth map i...
