Behavior Recognition with HMM and Feature Analysis using a Wide-view Camera and a PTZ camera
نویسندگان
چکیده
This paper proposes a method for recognizing human behaviors based on a combination of “overall motion analysis using Hidden Markov Model (HMM)” and “detailed feature analysis in a specific area by using an active (pan-tilt-zoom, PTZ) camera”. The PTZ parameters are controlled depending on the intermediate result of analyzing the target’s motions based on HMM. As a result, our system can distinguish between similar behaviors by observing high-resolution characteristic features (e.g., motion/shape). Experimental results demonstrated the effectiveness of the proposed system.

Camera Pose Estimation in Unknown Environments using a Sequence of Wide-Baseline Monocular Images
In this paper, a feature-based technique for the camera pose estimation in a sequence of wide-baseline images has been proposed. Camera pose estimation is an important issue in many computer vision and robotics applications, such as, augmented reality and visual SLAM. The proposed method can track captured images taken by hand-held camera in room-sized workspaces with maximum scene depth of 3-4...
متن کاملاستفاده از نمایش پراکنده و همکاری دوربین‌ها برای کاربردهای نظارت بینایی
With the growth of demand for security and safety, video-based surveillance systems have been employed in a large number of rural and urban areas. The problem of such systems lies in the detection of patterns of behaviors in a dataset that do not conform to normal behaviors. Recently, for behavior classification and abnormal behavior detection, the sparse representation approach is used. In thi...
متن کاملMoving Vehicle Tracking Using Disjoint View Multicameras
Multicamera vehicle tracking is a necessary part of any video-based intelligent transportation system for extracting different traffic parameters such as link travel times and origin/destination counts. In many applications, it is needed to locate traffic cameras disjoint from each other to cover a wide area. This paper presents a method for tracking moving vehicles in such camera networks. The...
متن کاملTowards on-line saccade planning for high-resolution image sensing
This paper considers the problem of designing an active observer to plan a sequence of decisions regarding what target to look at, through a foveal-sensing action. We propose a framework in which a pan/tilt/zoom (PTZ) camera schedules saccades in order to acquire high resolution images (at least one) of as many moving targets as possible before they leave the scene. An intelligent choice of the...
متن کاملPedestrians Tracking in a Camera Network
With the increase of the number of cameras installed across a video surveillance network, the ability of security staffs to attentively scan all the video feeds actually decreases. Therefore, the need for an intelligent system that operates as a tracking system is vital for security personnel to do their jobs well. Tracking people as they move through a camera network with non-overlapping field...
