The paper presents a wavelet-based method for medical image enhancement. A transfer function is derived for transferring wavelet coefficients at various multiresolution levels with different weighting values. Applications of the method to digital radiographic images of chest X-rays are shown. Moreover, in order to validate the effectiveness of the proposed method, we compare the results obtained using the wavelet analysis method to that using the conventional fast Fourier transform (FFT) method. The results show that the proposed method is superior to the FFT method in terms of image enhancement.
