Abstract :
It is difficult to reduce an NMR image´s ringing artifacts and obtain better images. This paper uses the method of dyadic wavelets and self-adaptive threshold to process the images that have the ringing artifacts. The test results prove that the method is effective and it can process the NMR image´s ringing artifacts. Finally the paper discusses using the fuzzy method
