Learning automatic video capture from human's camera operations

چکیده
This paper presents a video acquisition system that can learn automatic video capture from human’s camera operations. Unlike a predefined camera control system, this system can easily adapt to its environment changes with users’ help. By collecting users’ camera-control operations under various environments, the control system can learn video capture from human, and use these learned skills to operate its cameras when remote viewers don’t, won’t, or can’t operate the system. Moreover, this system allows remote viewers to control their own virtual cameras instead of watching the same video produced by a human operator or a fully automatic system. The online learning algorithm and the camera management algorithm are demonstrated using field data.

FlyCam: Practical Panoramic Video and Automatic Camera Control
This paper describes computationally and materially inexpensive methods for panoramic video imaging. Digitally combining images from an array of inexpensive video cameras results in a wide-field panoramic camera, from inexpensive off-the-shelfhardware. We present methods that both correct lens distortion and seamlessly merge images into a panoramic video image. Electronically selecting a region...
متن کاملIn-capture Mobile Video Distortions: A Study of Subjective Behavior and Objective Algorithms
Digital videos often contain visual distortions that are introduced by the camera hardware or processing software during the capture process. These distortions often detract from a viewer’s quality of experience. Understanding how human observers perceive the visual quality of digital videos is of great importance to camera designers. Thus, the development of automatic objective methods that ac...
متن کاملVideo Capture of Plastic Surgery Procedures Using the GoPro HERO 3+
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...
متن کاملCapturing Skeleton-based Animation Data from a Video
This paper presents a semi-automatic method to capture animation data from a single camera video. The video is first segmented and analyzed, and a 3D character model with skeleton rigged is input as a reference model. Then, the user modifies the reference model to fit the subject’s contour in the starting frame, and specifies the body and limbs contours of the subject character. Our system then...

This paper describes a new system for panoramic two-way video communication. Digitally combining images from an array of inexpensive video cameras results in a wide-field panoramic camera, from inexpensive off-the-shelf hardware. This system can aid distance learning in several ways, both by presenting a better view of the instructor and teaching materials to the students, and by enabling bette...
