摘　　要：提出了一种用于医学图像消噪的新型的小波阈值函数。改进的阈值函数是将两种常见的软、硬小波阈值函数相结合并加以改进,使其兼具了两者的滤波消噪特性。同时将改进的小波阈值函数应用在医学图像图像处理中,用于消除医学图像的噪声干扰,并利用仿真实验与软硬阈值函数作对比,从效果图和实验数据分析验证了其优势。Paper presents a novel wavelet threshold function.Modified wavelet threshold function combines and improves two classical-hard and soft threshold functions wavelet threshold functions, which contains better denoising proprites of these two fuctions. Futhermore, the fuction can be applicated by medical denosiong image application. And simulation experiement can compare these fuctions with the novel one, and can prove its advantage by rendering and experiment data analysis.
