摘要
该文介绍了实际应用场景中对钱塘江涌潮的检测方法,通过建立混合高斯模型来构建基于视频识别的涌潮背景模型,然后再利用所得的背景图像与当前视频帧进行相减,得到钱塘江潮水的前景图像,经过平滑去噪处理后,检测出涌潮信息。
This paper introduces a practical method of tidal detection in Qiantang river,and constructs the tidal background model based on video identification through establishing mixture Gaussian model.Then use the background difference between income background images and the current video frame so as to gain the foreground image of the moving object.Tidal will be detected after the noise removing processing.
