基于一种新小波变换的OCT图像去噪方法
Denoising method for OCT image based on combination of wavelet tranform with wiener filtering
摘要
Abstract
Speckle phenomenon is both as an information carrier and as noise resource in OCT image. According to this characteristics, a new image denoising method is presented by combining wavelet transform and wiener filter in this paper. OCT image is decomposed to four frequency sub-band images by wavelet tranform, among the different-band images, the three hight frequency sub-band images are denoised by Wiener filter, while keeps the low frequency image without any change, the three hight frequency detail images with Wiener filter and low frequency image are composed. The experimental results show this method is effective.关键词
