中文说明：应用背景小波变换在图像处理中的应用及其广泛，而对于图像去噪的处理一直是科研人员的难题，针对于此，提出了设置阀值的小波去噪，该方法是对于直接用小波去噪的提升。关键技术利用小波的多尺度的分解，然后设置阀值进行去噪处理，设置阀值有设置硬阀值和软阀值两种，硬阀值是这个计算阀值，然后进行比较，软阀值是一个变化的阀值，再对其进行处理。
English Description：
Application backgroundAnd widely application of wavelet transform in image processing, and for image de noise processing is always the problem of scientific research personnel, in light of the proposed wavelet denoising threshold setting, the method is to enhance the direct wavelet denoising.Key TechnologyUsing the wavelet multi-scale decomposition, then set a threshold denoising, setting the threshold set hard threshold and soft threshold two, hard threshold is the threshold calculation, then compared and soft threshold is a variation of the threshold, then carries on the processing.
