对小波图像去噪方法的探讨

On the Wavelet Image Denoising

小波图像去噪方法已广泛应用于图像去噪领域.在对目前小波图像去噪文献进行综合的基础上,描述了信号奇异性,并阐述了三种基于小波阈值去噪的方法,最后对小波去噪方法进行了一些展望.

Wavelet image denoising has been widely applied in image denoising.Based on many literatures of wavelet denoising,the paper investigated the singularities of signals and noises,and describes two methods to select threshold in wavelet transform.Then it classifies wavelet threshold denoising methods into three classes,and describes them respectively in theory,steps,and advantages.Finally,the future trend of wavelet denoising is pointed out.
