摘要：Image de-noising continues to be an active research topic. Although state-of-the-art de-noising methodsare numerically impressive and approach theoretical limits, they suffer from visible artifacts. However, the imagesobtained from medical imaging techniques (MRI, Ultrasound, CT etc.,) often include imaging noises. Therefore denoisingis an essential and used as a preprocessing process to remove their noises before extracting some meaningfulinformation from these images. In this paper presents an efficient de-noising technique based on Anisodiffusion filterwith Discrete Wavelet Transform (DWT) is developed. This proposed method enhances the edges in the de-noisedimage. The proposed method is tested with MRI, Ultrasound, and CT scan medical images. The performance of thismethod is compared with the existing standard filters and it has produced good result
