Characteristic extraction of stereoscopic images are difficult because of its huge data and dependence on the development of the human Visual System (HVS). However, in this paper some characteristics of stereoscopic images are proposed. We provides insight into absolute difference information and disparity information of 3D images, which can represent 3D images in a way.
A quality assessment method of stereo images is proposed firstly, which is based on the theories and methods of planar quality assessment-SSIM. It takes stereo (three-dimensional) vision into account, including the physiological stereoscopy and the psychological stereoscopy. Dense disparity of stereo images is extracted, then division into segments is carried out . The weighted structural similarity...
The understanding and estimation of stereo images are very important. There are many models of human visual system for planar image. It is blank for stereo image. An estimation of stereo image quality is proposed based on a multiple channel human visual system (HVS) for use in image compression .The model is based on a plane model, but has some modifications that make it is more suitable to stereo...
This paper proposes a novel framework for the compression and transmission of the auto-stereo video. Based on the video-plus-depth data representation, this framework provides high adaptability, reliability and flexibility for the stereo display. Besides, it also permits the consumers to be interactive with the perception of the stereo video. The proposed compression approach for the video-plus-depth...
In this paper, we present a novel stereo matching algorithm to create the dense disparity map for 3DTV processing line. We propose and analyze the Gaussian disparity distribution model first. Based on this model, we design the novel composite window for the window-based local optimization algorithm. An effective edge detection operator is first applied to get the object boundaries and avoid the detection...
In this paper, we present a novel objective approach to evaluate the disparity map quality. The two indices which are disparity gradient and disparity acceleration are first proposed for the evaluation of the disparity map. These two indices are under the assumption that the disparity map should be smooth in the natural scene. The joint application of the two indices guarantees the effective and reliable...
This paper presents a stereo matching algorithm which combines the genetic algorithm with the disparity propagation scheme to generate the dense disparity map. We design the detailed steps of genetic algorithm to realize the main stereo matching process. In order to increase the efficiency of this algorithm and improve the quality of the disparity map, we only perform it on the lower resolution image...
Several metrics have been proposed in literature to assess the quality of 2D images, but the metrics devoted to quality assessment of stereoscopic images are very scarce. Therefore, in this paper, an objective assessment method is proposed to predict the quality level of stereoscopic images. This method assesses stereo images from the perspective of image quality and stereo sense. Experiments demonstrate...
Pervasive computing enables people to obtain all kinds of information at any time and place. In this paper, considering the embedded device which is the key technology of the pervasive computing, it uses the Nios II embedded soft core processor to realize the central control part of digital satellite receiver. Utilizing the hardware customized characteristic of Nios II, this paper promotes a central...
