摘要
为了更好地消除水下声纳图像噪声及保持图像边缘效果,提出将Curvelet变换方法应用在水下图像去噪技术中.该处理方法克服了Ridgelet去噪只对直线边缘敏感的缺点,并对图像中存在的曲线特征起到了很好的边缘保持效果,并在实验输出数据比较中获得较好效果.
To remove the noise of the underwater sonar image and keep the edge effect of the image well, the Curvelet transform is used in the denosing of the underwater sonar image. The method overcomes the disadvantage of Ridealat denoising which is only sensitive to straight edge, receiving good edge-reserving effect. The experimental output data show the good results.
