小波阈值算法在图像去噪中的应用

his paper mainly studies on the image denoising technology based on the wavelet threshold algorithm, by selecting the appropriate wavelet, the two-dimensional images are decomposed by the wavelet, and then quantify the threshold, the images are reconstructed then. After the recovery, quality assessment is carried on between the wavelet algorithm and mean filtering and median filtering. The outcome of the experiment indicates that the wavelet thresholding algorithm has better recovery effect than other ways.
