Denoising Process of OCT Image Based on Wavelet Transform
小波变换对OCT图像的降噪处理

Sources and cherecteristics of noises are analysed in optical coherence tomography(OCT) system,and influences are given on image of these noises, the method of wavelet transform combining soft threshold filtering is introduced for denoising image.The definition of image is enhanced and the image quality is improved after process.It is shown that image noises can be reduced by this method.
