| Abstract: | The characteristics of wavelet transform and its significance in image edge extraction are presented.The detailed steps for the extended target c entroid calculation with wavelet transform are described.Extracting target(airp la ne) centroid coordinates when airplane images are in the background noise condit ions with different image fuzzy degrees by using wavelet transform,the extracti ng accuracy for target centroid coordinates under the different image fuzzy degr ees and background noise conditions are compared.The application prospect of wav elet transform in the extended target tracking is shown. |
