| Abstract: | A robust wavelet domain noise filtering method for medical images was proposed.The method was adapted to various kinds of noise,and a single parameter was used to balance the degree of noise reduction and preservation of relevant details as well as the choice of medical experts.The proposed method is of low complexity and the results show its efficiency in medical image denoising. |
