| Abstract: | A SAR ocean image data enhancement system based on the wavelet transformation is represented, and implemented. This system includes functions of wavelet transformation, Speckle and Pepper-Salt denoising, ship targets obtaining, internal wave obtaining, target characteristics and image zoom. The system can enhance some image with Gaussian noise, Speckle and Pepper-Salt non Gaussian noise, and image of microwave, optical sensors, such as SAR image. It has a variety of applications. |
