This dissertation deals with the image-based approach to synthesize a virtual scene using sparse images or a video sequence without the use of 3D models. In our scenario, a real dynamic or static scene is captured by a set of un-calibrated images from different viewpoints. After automatically recovering the geometric transformations between these images, a series of photo-realistic virtual view...

View synthesis is an efficient solution to produce content for 3DTV and FTV. However, proper handling of the disocclusions is a major challenge in the view synthesis. Inpainting methods offer solutions for handling disocclusions, though limitations in foreground-background classification causes the holes to be filled with inconsistent textures. Moreover, the state-of-the art methods fail to ide...

A new algorithm is proposed for novel view generation in one-toone teleconferencing applications. Given the video streams acquired by two cameras placed on either side of a computer monitor, the proposed algorithm synthesises images from a virtual camera in arbitrary position (typically located within the monitor) to facilitate eye contact. Our technique is based on an improved, dynamicprogramm...

Since virtual education has been considered as an alternative for conventional education and it is in progress in M. A. levels in Payam-e Noor University (PNU) the feasibility assessment of B.A. levels has been studied for the present study. In this study, the facilities and equipment needed for virtual education and the shortcomings of it in PNU is studied. The research is of practical ones an...

In the paper, two preprocessing methods for virtual view synthesis are presented. first approach, both horizontal and vertical resolutions of real views corresponding depth maps doubled in order to perform on images with densely arranged points. second method, filtered eliminate blurred or improperly shifted edges objects. Both performed prior synthesis, thus they may be applied different Depth...

Virtual view synthesis from an array of cameras has been an essential element of three-dimensional video broadcasting/conferencing. In this paper, we propose a scheme based on a hybrid camera array consisting of four regular video cameras and one time-of-flight depth camera. During rendering, we use the depth image from the depth camera as initialization, and compute a view-dependent scene geom...

background: in-service training courses are one of the most available programs that are used to improve the quantity and quality level of the staff services in various organizations, including libraries and information centers. with the advent of new technologies in the field of education, the problems and shortcomings of traditional in-service training courses were replaced with virtual ones. ...

This paper presents a method for generating synthetic views of a soccer ground starting from a single uncalibrated image. The relative affine structure of the players is computed by exploiting the knowledge of the soccer ground geometry and the fact that the players are in vertical positions. Then, novel views are generated using the “plane+parallax” representation to reproject points.
