Scene structure analysis for sprint sports
This work proposes a robust model to analyse the structure of horse races based on 2D velocity vector information. This model is capable of detecting scene breaks, classifying the view of the contenders and extracting the trajectory of the contenders throughout the race. The performance of the system is tested over six video clips from two different broadcast sources. The performance analysis shows the model achieves a high accuracy of view classification with the lowest value of 83%, all in real time
Macroblock Classification Method for Video Applications Involving Motions
In this paper, a macroblock classification method is proposed for various
video processing applications involving motions. Based on the analysis of the
Motion Vector field in the compressed video, we propose to classify Macroblocks
of each video frame into different classes and use this class information to
describe the frame content. We demonstrate that this low-computation-complexity
method can efficiently catch the characteristics of the frame. Based on the
proposed macroblock classification, we further propose algorithms for different
video processing applications, including shot change detection, motion
discontinuity detection, and outlier rejection for global motion estimation.
Experimental results demonstrate that the methods based on the proposed
approach can work effectively on these applications.Comment: This manuscript is the accepted version for TB (IEEE Transactions on
