Research on Detection and Tracking of Player in Broadcast Sports Video
Yang Wang,Yueqiu Han,Deming Zhang 보안공학연구지원센터 2014 International Journal of Multimedia and Ubiquitous Vol.9 No.11
The paper presents a method which bases on support vector machine(SVM) and particle filtering for detecting and tracking player in the broadcast sports video. Firstly, through the combination of Support Vector Classification and CourtSegmentationmethod, it proposes the algorithm for examining automatically members in those videos, which is used to initialize the trace of subsequent visual objects; secondly, by combing support vector regression frame and the one of sequential Monte Carlo, it brings forth the improved particle filtering algorithm which is applied to follow visual objects, enabling the traditional particle filtering method to achieve robust trail of such targets even when the particle set is small, together with effective enhancement of the running efficiency of tracking system.

The design of urban residential buildings in cold region is different from that in low latitude region, or the design of general public buildings. The precise grasp of dwelling unit type and appearance style, effective control of building heating and thermal insulation efficiency and the implementation of the sustainable concept of low cost construction and environmental protection are dependent on the early scientific and rational design. And the building information model technology just acts as a platform for the optimization of the design. The study is based on the engineering projects; the planning, the design of building facade, collision detection optimization and the full participation of construction cost control in building information model provide a new train of thoughts and research reference for the residential design in cold region, in the context of the digital age, and to a certain extent, the study looks forward to the future urban residential design and construction industrialization prospect in the cold region . Building information modeling technology improves the design efficiency and quality with its precise data processing and analysis, avoids the defects in design and the material waste of construction and environment pollution, significantly enhancing the pre-processing level of construction structure parts, which is in line with the energy-saving environmental protection and rural environmental construction phil
Research on Close Shot Segmentation in Sports Video

The basketball segmentation in close shots is studied. According to the consistency of basketball color, color segmentation is implemented. Then with the help of steerable filters, the method detects image edges and the orientations of them. Finally, based on edges and their orientations, Hough transform is improved to get the circle center and the radius of basketball.
