TL;DR: 3D volume reconstruction technology is the new sign of future technology and communications, it means that production costs should be minimal with a limited product environment and promising the glass free viewing.
Abstract: 3D volume reconstruction technology is the new sign of future technology and communications. In 2008 this technology first received attention worldwide by Prince Charles addressed the World future energy summit and made his first appearance as a hologram in a bid to reduce the royal carbon footprint. In past it is known as the pepper's ghost technique. The same way using the light illusion ghost is made at the stage. Now this technology has been used improved and create fun. It means that production costs should be minimal with a limited product environment and promising the glass free viewing. It has various application in every fields of business, education, telecommunication and healthcare, etc.

TL;DR: This paper proposes a system along with a working prototype of such intelligent system that essentially is a Chatbot which uses facility of Theme Detection in semantic analysis stage while processing the user input to make the system more productive.
Abstract: Intelligent systems are the need of today’s world. Collections of data and various data sets are made available to naive users. Understanding what is contained within the dataset is quite difficult by referring just the name. Some of the datasets have quite a difficult, weird names so users do not have any clue what is inside, so there is a need of the theme of the document or dataset so as to understand what are the contents. User satisfaction and convenience is of prime importance. In this paper, we try to propose a system along with a working prototype of such intelligent system that essentially is a Chatbot which uses facility of Theme Detection in semantic analysis stage while processing the user input. This makes the system more productive. This paper talks about Chatbot and improvement in intelligent responses using theme detection. We have built a prototype of the system.

TL;DR: Qualitative results demonstrate high quality reconstructions even visually comparable to active depth sensor-based systems such as KinectFusion, making such systems even more accessible.
Abstract: MonoFusion allows a user to build dense 3D reconstructions of their environment in real-time, utilizing only a single, off-the-shelf web camera as the input sensor. The camera could be one already available in a tablet, phone, or a standalone device. No additional input hardware is required. This removes the need for power intensive active sensors that do not work robustly in natural outdoor lighting. Using the input stream of the camera we first estimate the 6DoF camera pose using a sparse tracking method. These poses are then used for efficient dense stereo matching between the input frame and a key frame (extracted previously). The resulting dense depth maps are directly fused into a voxel-based implicit model (using a computationally inexpensive method) and surfaces are extracted per frame. The system is able to recover from tracking failures as well as filter out geometrically inconsistent noise from the 3D reconstruction. Our method is both simple to implement and efficient, making such systems even more accessible. This paper details the algorithmic components that make up our system and a GPU implementation of our approach. Qualitative results demonstrate high quality reconstructions even visually comparable to active depth sensor-based systems such as KinectFusion.

TL;DR: The combined presence of motion parallax and stereoscopic cues significantly improved the accuracy with which participants were able to assess gaze and hand pointing cues, and to instruct others on 3D body poses.
Abstract: In this paper, we present TeleHuman, a cylindrical 3D display portal for life-size human telepresence. The TeleHuman 3D videoconferencing system supports 360 degree motion parallax as the viewer moves around the cylinder and optionally, stereoscopic 3D display of the remote person. We evaluated the effect of perspective cues on the conveyance of nonverbal cues in two experiments using a one-way telecommunication version of the system. The first experiment focused on how well the system preserves gaze and hand pointing cues. The second experiment evaluated how well the system conveys 3D body postural information. We compared 3 perspective conditions: a conventional 2D view, a 2D view with 360 degree motion parallax, and a stereoscopic view with 360 degree motion parallax. Results suggest the combined presence of motion parallax and stereoscopic cues significantly improved the accuracy with which participants were able to assess gaze and hand pointing cues, and to instruct others on 3D body poses. The inclusion of motion parallax and stereoscopic cues also led to significant increases in the sense of social presence and telepresence reported by participants.

TL;DR: This work combines two active areas of research in computer vision: unsupervised object extraction from a single image, and depth estimation from a stereo image pair, and introduces the concept of 3D scene-consistency into stereo matching.
Abstract: This work combines two active areas of research in computer vision: unsupervised object extraction from a single image, and depth estimation from a stereo image pair. A recent, successful trend in unsupervised object extraction is to exploit so-called "3D scene-consistency", that is enforcing that objects obey underlying physical constraints of the 3D scene, such as occupancy of 3D space and gravity of objects. Our main contribution is to introduce the concept of 3D scene-consistency into stereo matching. We show that this concept is beneficial for both tasks, object extraction and depth estimation. In particular, we demonstrate that our approach is able to create a large set of 3D scene-consistent object proposals, by varying e.g. the prior on the number of objects. After automatically ranking the proposals we show experimentally that our results are considerably closer to ground truth than state-of-the-art techniques which either use stereo or monocular images. We envision that our method will build the front-end of a future object recognition system for stereo images.

TL;DR: Telepresence, an emerging teleconferencing technology that's designed to not only connect people together but to make them feel like they're all collaborating together inside the same room, is introduced.
Abstract: Imagine a teleconferencing system that's so realistic, so natural, that you feel you could reach out and shake a participant's hand, even though the individual may be sitting in a room hundreds or even thousands of miles away. That's the idea behind telepresence, an emerging teleconferencing technology that's designed to not only connect people together but to make them feel like they're all collaborating together inside the same room.

TL;DR: Zhang et al. as mentioned in this paper proposed telepresence, an emerging teleconferencing technology that was designed to connect people together and to make them feel like they were all collaborating together inside the same room.
Abstract: Imagine a teleconferencing system that’s so realistic, so natural, that you feel you could reach out and shake a participant’s hand, even though the individual may be sitting in a room hundreds or even thousands of miles away. That’s the idea behind telepresence, an emerging teleconferencing technology that’s designed to not only connect people together but to make them feel like they’re all collaborating together inside the same room. Telepresence provides an immersive meeting experience based on the highest possible levels of audio and video clarity. Ideally, participants are life-sized. Ide ally, every sound, gesture, and facial expression are replicated in high-definition (HD) video and high-fidelity surround sound. The ultimate goal is to make telepresence and in-person meetings virtually indistinguishable from each other. “Telepresence has a great potential for getting people to work together collaboratively, efficiently, and naturally regardless of their physical location,” observes Zhengyou Zhang, a principal researcher focusing on telepresence technologies at Microsoft Research in Redmond, Washington. With business becoming increasingly global, and travel getting ever more expensive and cumbersome, telepresence’s popularity is soaring.
