Video Stabilizing and Tracking by Horizontal Line for Maritime Cruise Ship

It is a key technique to carry out video Stabilizing and object tracking in the Held of marine supervision. This method is based on the new requirements of maritime law enforcement ship. Firstly, It resolve the detection of horizontal line with wavelet transformation. Then, by the combination of horizontal line, image transformations and video platform´s feedback, a algorithm of dual compensatory video stabilizing (DCVS) is carried out. Synchronously, with the ubiety of truncation-center and global coordinate system, Kalman filter is used to carry on estimating Truncation-center to finished truncation tracking (TT) of video object. Because it make full use of hydraulic parameters of horizontal line to achieve video stabilizing and tracking, the technique performs well.
