Automated video production system and method using expert video production rules for online publishing of lectures

Abstract: An automated system and method for producing videos using expert video production rules. The automated video production system and method of the present invention is particularly well-suited for the online publishing of lectures. The system of the present invention includes a camera system for capturing the lecture, such as an audience-tracking camera and a non-intrusive lecturer-tracking camera. Moreover, each camera may be controlled by a cinematographer. Tracking of a subject is performed using a history-based, reduced-motion tracker that sets up a camera shot based on the subject's movement history and leaves the shot fixed until the camera is switched. The system also includes a virtual director module having a probabilistic finite state machine (FSM) module that uses probabilistic rules and the expert video production rules to determine a current camera view.

Miniaturized smart cameras for 3D-imaging in real-time [mobile robot applications]

Abstract: While our world is three-dimensional, today's cameras only allow for the acquisition of images that are two-dimensional. This paper presents a novel miniaturized 3D camera that delivers range images in video real-time. The camera is based on the time-of-flight (TOF) principle and under optimum conditions achieves a distance resolution of a few mm over a measurement range of several meters. The ability to capture the entire environment in three dimensions represents completely new possibilities, and many applications are expected to directly profit from this powerful imaging technology. In particular, in the field of mobile robotics, miniaturized 3D cameras enable the solution of navigation problems, such as obstacle avoidance, map building, localization, and path planning.

Smart camera system

Abstract: There is provided a smart camera (20) including: (a) a pixel sensor (110); (b) optical imaging means (100) for projecting an image of a scene onto the sensor (110) to generate a sensor signal representative of the scene; (c) processing means (120, 140) for processing the sensor signal to identify whether or not one or more events occur within the scene and for outputting an output signal indicative of occurence of one or more of the events to a communication channel coupled to the processing means The camera (20) is deitinguished in that it includes communication means (30, 130) for remotely updating at least one of operating parameters and software of the processing means (120, 140) for modifying operation of the camera for identifying the events

Multi-function on-board camera system and image display method of multi-function on-board camera system

Abstract: PROBLEM TO BE SOLVED: To provide a multi-function on-vehicle camera system capable of displaying images for safe drive support in appropriate timings depending on driving conditions and in a form easy for a driver to understand. SOLUTION: In a multi-function on-vehicle camera system provided with plural on-vehicle cameras 11-18 and monitors 19-21 to display camera images, an image process means 47 to process camera image and a system control means 42 to specify camera images used for image processing and the form of image processing in the image process means 47 in response to signals 37-41 indicating vehicle conditions are arranged. Images for supporting safe drive are displayed in appropriate timings depending on driving conditions and in form easy for a driver to understand.

Securing embedded smart cameras with trusted computing

Abstract: Camera systems are used in many applications including video surveillance for crime prevention and investigation, traffic monitoring on highways or building monitoring and automation. With the shift from analog towards digital systems, the capabilities of cameras are constantly increasing. Today's smart camera systems come with considerable computing power, large memory, and wired or wireless communication interfaces. With onboard image processing and analysis capabilities, cameras not only open new possibilities but also raise new challenges. Often overlooked are potential security issues of the camera system. The increasing amount of software running on the cameras turns them into attractive targets for attackers. Therefore, the protection of camera devices and delivered data is of critical importance. In this work we present an embedded camera prototype that uses Trusted Computing to provide security guarantees for streamed videos. With a hardware-based security solution, we ensure integrity, authenticity, and confidentiality of videos. Furthermore, we incorporate image timestamping, detection of platform reboots, and reporting of the system status. This work is not limited to theoretical considerations but also describes the implementation of a prototype system. Extensive evaluation results illustrate the practical feasibility of the approach.
