Abstract :
In this paper, a new wavelet-based adaptive enhancement algorithm for MRI has been proposed. In the new algorithm, two non-linear adaptive rules have been used to enhance both of lower and higher frequency wavelets coefficients separately. The experiment results showed that enhanced images obtained by new algorithm have better contrast of gray levels and less noise comparing with results from other wavelet-based adaptive enhancement algorithms.
