一种改进的小波阈值去噪方法
An improved wavelet threshold denoising method
摘要
Abstract
On the basis of the original wavelet threshold denoising(WTD)method,an improved image denoising method (FastICA⁃MPSO⁃WTD) is proposed. The method combines the fast independent component analysis (FastICA) with wavelet threshold denoising(WTD)for image denoising. In order to make the effect of wavelet threshold denoising better,the modified particle swarm optimization(MPSO)is used to optimize the parameter of wavelet threshold. To demonstrate the effectiveness of the proposed method,a test image was selected to conduct the denoising contrast experiment,in which the peak signal⁃to⁃noise ratio (PSNR) was used to evaluate the denoising effect. The experimental results show that the improved method (FastICA⁃MPSO⁃WTD)can improve the denoising effect effectively.关键词
