    Summary form only given. Integral imaging is a rising 3D imaging technique that can be considered the incoherent version of holography. In integral imaging the multiperspective information of 3D scenes is stored in a 2D picture. Such picture, composed by a set of elemental images, is obtained through a 2D array of microlenses. The elemental-images set can be used for many purposes. One is the disp... View full abstract»

    We propose a natural 3D scene generation method using a TOF camera and real light information. We can generate 3D human actor by capturing a depth and color image of human actor using a TOF camera which uses the IR sensor. But the acquisition is processed in an indoor environment due to the time and space constraints of capturing environments. In practice, a composition using a 3D human actor with...

    Multi-view video allows user to watch 3D video and select desired viewpoint. In order to reduce the switching delay, many researches tend to transmit all the views, which brings much more increment in the bandwidth requirement. And the traffic increase as the increase of the number of the views in the multi-view video. In order to overcome these problems, we have proposed a user dependent scheme c... View full abstract»

    We present a new method for fully automated video matting. This method uses depth information acquired by a depth camera to automatically compute trimaps. Trimaps segment an image into three nonoverlapping regions (foreground, background, and unknown) and generation of a highly accurate trimap is one of the most important tasks in natural alpha matting. We propose an adaptive approach to generate ... View full abstract»

    The multi-view video coding (MVC) standard includes all the highly advanced techniques of H.264/AVC. Especially, the techniques employed in motion estimation are extended to reduce not only temporal but inter-view redundancies in MVC, but motion vector prediction of a skip mode is only performed in a temporal direction. Therefore, we introduce a temporal skip mode using reference pictures at the s... View full abstract»

    The quality of depth maps is crucial for 2D to 3D conversion, but high quality depth map generation methods are usually very time consuming. We propose an efficient semi-automatic depth map generation scheme based on limited user inputs and depth propagation. First, the original image is over-segmented. Then, the depth values of selected pixels and the approximate locations of T-junctions are spec... View full abstract»
