  • Image-de-noising-algorithm-using
    提出了一种基于非下采样Contourlet 变换的自适应图像去噪方法 首先对噪声图像进行非下采样Contourlet 变换,得到各 个尺度各个方向子带的系数,再根据该系数的能量自适应地调整去噪阈值 实验表明,与Contourlet 多尺度阈值去噪 Contourlet 自 适应阈值去噪相比,该方法在保留图像边缘细节的同时,能提高图像的PSNR 值,减少了Gibbs 现象(A new adaptive method of image de-noising based on NonSubsampled Contourlet Transform (NSCT)is presented.Firstly, the noisy image is decomposed into a set of multiscale and multidirectional frequency subbands by NSCT, and then the threshold is adapted automatically according to the energy of subband coefficients.Compared with the multi-scale threshold using contourlet transform and using adaptive threshold based on contourlet transform, the simulation results show that the performance of this method is superior in PSNR, meanwhile it can maintain the image edge and reduce the Gibbs phenomen)
