Local stereo matching as a main category of stereo methods has been studied for decades. Recently, there appeared some well-performed local stereo methods and these state-of-the art methods show comparable performance in terms of quality and better performance in terms of speed with global methods on the Middlebury datasets. However, previous surveys of stereo matching do not consider disparity refinement...
High-resolution 3D reconstruction has become increasingly important due to its wide applications such as 3D printing, entertainment, engineering etc. In this paper, a high-resolution 3D reconstruction system based on structured light is proposed. Our proposed system contains a consuming projector and a digital camera. Unlike the traditional structured light which directly projects patterns into scenes,...
The fast development of time-of-flight (ToF) cameras in recent years enables capture of high frame-rate 3D depth maps of moving objects. However, the resolution of depth map captured by ToF is rather limited, and thus it cannot be directly used to build a high quality 3D model. In order to handle this problem, we propose a novel joint example-based depth map super-resolution method, which converts...
It attracts many researchers' attention to find a stereo matching algorithm both accurate and fast. Yoon and Kweon's Adaptive Support-Weight(ASW) method is supposed to be a very successful algorithm in both accuracy and speed. However, it is very time consuming for ASW to take a large number of pixels into consideration for computing a disparity. In this paper, we present a stereo matching algorithm...
In 3D video transmission, the depth map is normally compressed by resolution reduction to save bandwidth. The lost information in resolution reduction is recovered by an appropriate upsampling algorithm in decoding step. Most previous work considers the depth upsampling problem as common 2D map upsampling problem and do not take the intrinsic property of depth map into consideration. In this paper,...
The feature of rendering arbitrary view make layered depth image (LDI) be able to present multi-view video data and provide enhanced interactivity, such as free view video (FVV). However, visual artifacts occurred in the rendered result limit the practicality of LDI. In this paper, we proposed an approach to deal with this problem, which refines colors of the depth pixels by clustering to remove matting...
