摘要
提出了一种基于第二代curvelet变换的图像增强算法。该算法结合NeighShrink去噪方法,适当的调整curvelet的系数,在去噪的同时达到增强的效果。不同增强方法的比较试验表明,该算法是图像增强的有效方法。
A new algorithm for image enhancement was presented based on the second curvelet transform. Based on the NeighShrink denoising method, the curvelet coefficients were properly modified and various enhancement methods were given. The results show that the algorithm is an effective method of image enhancement.
