We set basic one-dimensional and two-dimensional images, and add four types of noises on different levels. We will denoise these corrupted images by using total variation, soft-thresholding and adaptive median filter, respectively. Finally, compare the PSNR values to analyse the denoising effect, edges preserving, and blurring.1507218 bytesapplication/pdfen-US去雜訊小波全變差軟式閾值適應性中間值濾波器DenoisingWaveletSoft-thresholdingTVAdaptive Median Filterthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/249844/1/ntu-99-R95221023-1.pdf
