报告简介：

Visual infrastructure, consisting of connected visual sensors, has been extensively deployed and serving various important applications, such as safety surveillance, health monitoring and mobile system navigation. However, there are still many remaining problems due to visual sensing model irregularity, image processing complexity, and environmental noise etc. In this talk, we focus on the following three related problems: Visual infrastructure deployment: we propose local face-view barrier coverage, i.e. L-Faceview, a novel concept that achieves statistical barrier coverage in visual sensor networks leveraging mobile object's trajectory information. We derive a rigorous probability bound for this coverage via a feasible deployment pattern. Visual infrastructure based object recognition: we design and implement R-Focus, a platform with visual sensors that can detect and verify a person holding a mobile phone in proximity with the assistance of electronic sensors. R-Focus performs visual and electronic data collection and rotates based on the collected data. It integrates both visual and electronic data for accurate object recognition. Visual infrastructure based object localization: we design Flash-Loc, an accurate indoor localization system leveraging flashes of light to localize objects in areas with deployed visual infrastructure. Flash-Loc consists of three key mechanisms that distinguish objects while avoiding long irritating flashes: adaptive-length flash coding, pulse width modulation based flash generation, and image subtraction based flash localization. This talk will discuss the above techniques along with the system implementation and solutions to practical challenges.
