A New Algorithm of Moving Target Detection in Image Sequence Based on the Lifting Scheme
基于小波提升框架的图像序列中运动目标检测算法

In surveillance system, moving target detection in image sequence is a very significant and difficult problem. The objective of this research was to present a new detection method to enhance the efficiency and accuracy of moving target recognition,and to resolve the difficulties brought by target distortion. The detail theory and algorithm of a new detection method, which was based on the lifting scheme of wavelet and deformable template technique, were described. The multi-scale images were used to improve the target matching efficiency, and the deformable templates were used to tracking the target distortions. The results indicated that the moving objects detected by the new method based on the lifting scheme were more robust than those detected by traditional methods. In addition, the detection speed became more rapid. The results seem to suggest that the new method be with efficiency and accuracy advantages in computer version.
