Detection and Tracking of Moving Objects for Mosaic Image Generation
نویسندگان
چکیده
Mosaic images provide an eecient representation of image sequences and simplify scene exploration and analysis. However, the application of conventional methods to generate mosaics of scenes with moving objects causes integration errors and a loss of dynamic information. In this paper a method to compute mosaics of dynamic scenes is presented addressing the above mentioned problems. Moving pixels are detected in the images and not integrated in the mosaic yielding a consistent representation of the static scene background. Furthermore, dynamic object information is extracted by tracking moving regions. To account for unavoidable variances in region segmentation topologically neighboring regions are grouped into sets before tracking. The regions' and objects' motion characteristics are described by trajectories. Along with the background mosaic they provide a complete representation of the underlying scene which is idealy suited for further analysis.

متن کاملStatistical Background Modeling Based on Velocity and Orientation of Moving Objects
Background modeling is an important step in moving object detection and tracking. In this paper, we propose a new statistical approach in which, a sequence of frames are selected according to velocity and direction of some moving objects and then an initial background is modeled, based on the detection of gray pixel's value changes. To have used this sequence of frames, no estimator or distribu...

متن کاملA Novel Method for Tracking Moving Objects using Block-Based Similarity
Extracting and tracking active objects are two major issues in surveillance and monitoring applications such as nuclear reactors, mine security, and traffic controllers. In this paper, a block-based similarity algorithm is proposed in order to detect and track objects in the successive frames. We define similarity and cost functions based on the features of the blocks, leading to less computati...
