Mobile phone camera-based document video scanning is an interesting research problem which has entered into a new era with the emergence of widely used, processing capable and motion sensors equipped smartphones. We present our ongoing research on mobile phone camera-based document image mosaic reconstruction method for video scanning of paper documents. In this work, we have optimized the clas...

In this paper, we present a method to calibrate and enhance depth information captured by an infrared (IR)-based time-of-flight video-plus-depth camera called “Kinect camera”. For depth data calibration, we use color and IR images of a chessboard with on-off halogen light sources to calculate camera parameters of the video and IR sensors in the Kinect camera. For depth data enhancement, we intr...

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...

The MIC IP dynamic 7000 HD camera has an advanced PTZ platform that was designed using Bosch’s domain expertise in material engineering, mechanical design, intelligent imaging, and video streaming. The camera complies to some of the toughest industry standards such as IP68, NEMA 6P, and IK10 for extreme mechanical strength and durability. The camera is designed using the latest technology in in...

OVERVIEW: A camera system is developed for delivering real-time video streams over corporate intranets, the Internet, and other networks. The system encompasses TCP/IP-compliant cameras that can be directly connected to networks, representative application software for the PC side, application-specific APIs, and an environment enabling customers to customize application software. The applicatio...

Omnidirectional multi-camera systems cannot capture entire fields of view because of their inability to view areas directly below them. Such invisible areas in omnidirectional video decrease the resulting realistic sensation experienced when using a telepresence system. In this study, we generate omnidirectional video without invisible areas using an image completion technique. The proposed met...

Compressed video processing for the sake of content based retrieval saves time of the expensive decoding. In this paper , we process the compressed MPEG video data for the motion analysis of its contents. Two motion components are differentiated from each other. Firstly, the object's motion; the change in object’s co-ordinate throughout consecutive frames. Secondly, the camera motion resulting ...

BACKGROUND Significant improvements can be made in recoding surgical procedures, particularly in capturing high-quality video recordings from the surgeons' point of view. This study examined the utility of the GoPro HERO 3+ Black Edition camera for high-definition, point-of-view recordings of plastic and reconstructive surgery. METHODS The GoPro HERO 3+ Black Edition camera was head-mounted o...

Models of real-world objects and actions for use in graphics, virtual and augmented reality and related fields can only be obtained through the use of visual data and particularly video. This paper examines the question of recovering shape models from video information. Given video of an object or a scene captured by a moving camera, a prerequisite for model building is to recover the three-dim...

A method based on computer vision technologies is presented to achieve the function that the simulated motion in sport simulation system and the motion in sport video are presented on the same screen and at the same view point. The proposed method first applies the camera self-calibration theory to obtaining camera intrinsic parameters in sport video according to the 2D video features correspon...
