MRI image denoising based on improved wavelet thresholding
Xing Hao-yang · Journal of Computer Applications · 2007
A scheme based on the improved wavelet threshold for the noise removal in Magnetic Resonance Image (MRI) images was presented. In this paper, the wavelet threshold method was improved according to the characteristics of MRI images and according to neighboring threshold of wavelet coefficients, conquering the limitation of using traditional wavelet transform. The experimental result indicates that the algorithm can maintain the details of the MRI images while removing the noise, in favor of doctors' diagnosis.
