A tertiary goal, which we plan to explore in depth in future research, is the integration of image compression with automated target recognition (ATR). Two cases are of interest to this study. First, we have shown that one can achieve increased processing efficiency by applying specially configured ATR operations to compressed imagery [Sch97c,d]. Second, we have developed techniques for prefilt...

Background and Objectives: Action recognition, as the processes of labeling an unknown action of a query video, is a challenging problem, due to the event complexity, variations in imaging conditions, and intra- and inter-individual action-variability. A number of solutions proposed to solve action recognition problem. Many of these frameworks suppose that each video sequence includes only one ...

This paper introduces a video sharing platform based on WiFi, which consists of camera, mobile phone and PC server. This platform can receive wireless signal from the camera and show the live video on the mobile phone captured by camera. In addition, it is able to send commands to camera and control the camera’s holder to rotate. The platform can be applied to interactive teaching and dangerous...

We aim at the realization of automatic contents production system of commentary soccer video based on digital shooting technique which is composed of digital camera work and digital switching technique. The digital camera work is defined as virtual panning and virtual zooming. the virtual panning is a video production technique of clipping a size fixed frame by controlling frame location on a h...

Conventional video cameras have limited elds of view that make them restrictive in a variety of vision applications. There are several ways to enhance the eld of view of an imaging system. However, the entire imaging system must have a single eeective viewpoint to enable the generation of pure perspective images from a sensed image. A new camera with a hemispherical eld of view is presented. Tw...

ÐThis paper deals with video-based augmented reality and proposes an algorithm for augmenting a real video sequence with views of graphics objects without metric calibration of the video camera by representing the motion of the video camera in projective space. A virtual camera, by which views of graphics objects are generated, is attached to a real camera by specifying image locations of the w...

Video is an effective teaching tool, and live video microscopy is especially helpful in teaching dissection techniques and the anatomy of small neural structures. Digital video equipment is more affordable now and allows easy conversion from older analog video devices. I here describe a simple technique for bringing digital video from one camera to all of the computers in a single room. This te...

A camera system has been developed to provide live 3D video input for a time-multiplexed autostereoscopic display. The system is capable of taking video input from up to sixteen sources and multiplexing these into a single video output stream with a pixel rate an order of magnitude faster than the individual input streams. Both monochrome and colour versions of the system have been built. Testi...

Digital videos often suffer from undesirable camera jitters because of unstable camera motions. In this paper we present a novel video stabilization algorithm by mixed L1-L2 optimization, aiming at removing unwanted camera movements as well as keeping the original video information to the greatest extent. In the proposed algorithm, we compute smoothed camera paths that are composed of constant,...
