基于平稳小波的X射线底片数字图像去噪方法研究
A X-Ray Negative Digital Image Denosing Method Based on Stationary Wavelet Transform
【摘要】 本文介绍了小波变换的基本内容,重点介绍了离散小波变换和平稳小波变换,并采用平稳小波变换对X光底片进行处理,将平稳小波与离散正交小波进行了对比实验。实验结果证明,利用平稳小波去噪具有较好的视觉效果,提高了被检对象缺陷的辨识率。
【Abstract】 The paper introduces the basic content of wavelet transform and presents the discrete wavelet transform and the stationary wavelet transform particularly.We take the experiment that uses the stationary wavelet transform to compare with the discrete orthogonal wavelet transform.The result proves that it takes good effect on vision to use the stationary wavelet transform,and the recognition rate of the disfigurement in the detected objects.
