Improved Thresholding Method in Image Wavelet Denoising

This paper explained the principle and algorithm realization of image multi-resolution threshold denoising of wavelet transform.A method of thresholding estimation is presented,this method is more exact in thresholding estimation than the classical thresholding denoising method,and realized thresholding denoising using the thresholding estimation method,the simulation results show that this method is better than the classical thresholding denoising methods in improving the PSNR value and subjective visual effects.
