In this paper, we propose an accelerated local feature extraction in a reuse scheme for action recognition. Most local features of the previous frame could be reused due to the high correlation between successive frames. Feature extraction is only needed to be applied partially in the current frame. The full-frame features of the current frame are combined by features extracted at different times...
2-D-to-3-D conversion is an important step for obtaining 3-D videos, as a variety of monocular depth cues have been explored to generate 3-D videos from 2-D videos. As in a human brain, a fusion of these monocular depth cues can regenerate 3-D data from 2-D data. By mimicking how our brains generate depth perception, we propose a reliability-based fusion of multiple depth cues for an automatic 2-D-to-3-D...
The concept of perceptual integration of multiple depth cues is proposed for converting 2D videos to 3D videos. Several monocular depth cues have been explored to reconstruct 3D videos. We propose reliability-based promotion and fusion of depth cues for an automatic reconstruction of 3D videos in this demo by mimicking how human visual system does.
The three-dimensional (3D) displays provide a dramatic improvement of visual quality than the 2D displays do. However, for existed 2D contents, depth information is not recorded. Therefore, 2D-to-3D conversion is necessary. This paper presents an automatic system which convert 2D videos to 3D videos. The proposed system groups the blocks into regions using edge information. A prior hypothesis of depth...
The three-dimensional (3D) displays provide a dramatic improvement of visual quality over the 2D displays. The conversion of existing 2D videos to 3D videos is necessary for multimedia application. This paper presents an automatic and robust system to convert 2D videos to 3D videos. The proposed 2D-to-3D conversion combines two major depth generation modules, the depth from motion and depth from geometrical...
