In this work, we demonstrate a 3D DMB player which provides users with realistic 3D services over terrestrial-digital multimedia broadcasting (T-DMB). Since the bit-budget for the transmission of additional data stream is strictly limited in the current state of T-DMB, the 3D services are based on depth-image-based rendering (DIBR) that the depth information as the additional data can be compressed...
This paper presents a fast computation algorithm of binocular energy model (BEM) to estimate the global disparity between a pair of stereoscopic images. The previous methods estimated the global disparity by using the convolution of receptive field function and stereoscopic images. But, it is known that the above approaches take a long time to obtain the required output. Hence, in this paper, we propose...
In this paper, we present a depth image based rendering technique for 3D data service over T-DMB. 3D service over T-DMB is very attractive because the single user environment of T-DMB is suitable to glassless 3D viewing. However, the bit budget for depth transmission over T-DMB is very limited with 32 Kbps for data service. Depth image based rendering can resolve this problem because the corresponding...
A framework for virtual view synthesis based on multiple images is presented in this paper. Compared to conventional view synthesis based on stereoscopic image pairs, a postprocessing algorithm for disparity refinement is added to exploit information contained in multiple images captured with a multi-view camera configuration. The principle for disparity refinement is examined, leading to the development...
Image compression has many applications. For example, it is an important step for distributed and network based pattern recognition. For real time object recognition or reconstruction, image compression can greatly reduce the image size, and hence increase the processing speed and enhance performance. Fractal image compression is a relatively recent image compression method. Its basic idea is to represent...
