Denoising and Enhancement of Magnetic Resonance Image Based on the Dyadic Wavelet Analysis
Zheng Hoang Huang, Xia Li · Advanced materials research · 2012
This paper is applied non-linear operators for image enhancing. The efficient algorithm of MRI enhancement is provided by decomposition of localized information at different spatial frequencies. So the MRI edge textures was enhanced while suppresses the noise maximally. Experiment was show more obvious unseen or barely seen features, and the visual effect is improved after the method, and help for diagnosing the state of an illness.
