Auto-directed video stabilization with robust L1 optimal camera paths

Abstract: We present a novel algorithm for automatically applying constrainable, L1-optimal camera paths to generate stabilized videos by removing undesired motions. Our goal is to compute camera paths that are composed of constant, linear and parabolic segments mimicking the camera motions employed by professional cinematographers. To this end, our algorithm is based on a linear programming framework to minimize the first, second, and third derivatives of the resulting camera path. Our method allows for video stabilization beyond the conventional filtering of camera paths that only suppresses high frequency jitter. We incorporate additional constraints on the path of the camera directly in our algorithm, allowing for stabilized and retargeted videos. Our approach accomplishes this without the need of user interaction or costly 3D reconstruction of the scene, and works as a post-process for videos from any camera or from an online source.

A vision system for landing an unmanned aerial vehicle

Abstract: We present the design and implementation of a real-time computer vision system for a rotorcraft unmanned aerial vehicle to land onto a known landing target. This vision system consists of customized software and off-the-shelf hardware which perform image processing, segmentation, feature point extraction, camera pan/tilt control, and motion estimation. We introduce the design of a landing target which significantly simplifies the computer vision tasks such as corner detection and correspondence matching. Customized algorithms are developed to allow for realtime computation at a frame rate of 30 Hz. Such algorithms include certain linear and nonlinear optimization schemes for model-based camera pose estimation. We present results from an actual flight test which show the vision-based state estimates are accurate to within 5 cm in each axis of translation, and 5 degrees in each axis of rotation, making vision a viable sensor to be placed in the control loop of a hierarchical flight management system.

Wireless image transfer from a digital still video camera to a networked computer

Abstract: A portable image transfer system includes a digital still camera which captures images in digital form and stores the images in a camera memory, a cellular telephone transmitter, and a central processing unit (CPU). The CPU controls the camera memory to cause it to output data representing an image and the CPU controls the cellular telephone transmitter to cause a cellular telephone to transmit the data received from the camera memory. A receiving station is coupled to the cellular telephone transmitter by a cellular network to receive image data and store the images.

Intelligent multi-access system

Abstract: A multi-access remote system having a security surveillance area, a plurality of end user locations, and a communications network such that one or more of the end user locations can establish a connection with the security surveillance area, and vice versa, using a communications protocol via the communications network The security surveillance area is comprised of a local computer system, a camera with motion sensor, and a network interface When the motion sensor detects an obstruction the camera starts recording and the local computer system notifies a remote individual of the alarm via a communications device, such as a beeper, telephone, or e-mail Using an end user location, having a remote computer system, a network interface, and one or more communications devices, the remote individual can logon to the local computer system via the communications network and obtain additional information, control the video camera remotely, or view video images Access to the security surveillance area, control of the video camera, and viewing of the video data is accomplished advantageously over the Internet with application specific browser software, plugins, APIs, and other protocols

Android bound service camera initialization

Abstract: A mobile device includes a camera, a user interface system, and a processor communicatively coupled to the camera and the user interface system. The processor is typically configured for running a first application. The first application is typically configured for (i) accessing the camera, (ii) upon the initialization of the first application, initializing the camera, and (iii) maintaining the camera in an initialized state as long as the first application is running. The application may be further configured for focusing the camera and maintaining the camera in a focused state as long as the first application is running.
