Abstract
In the higher levels, wavelet compression smooths de data and preserves most diagnostic information in the images. It was found that the MTF performance along with the quality levels coincides well with that of the SNRs. This demonstrated the usefulness of the MTF as a means to assess image quality in compression. However, as the quality levels decreased, the effect of the diagonal artifact became predominant such that it distorted the higher frequency components of the image. The inverse MTF filter sharpened the image and enhanced the SNR. However, in using the inverse MTF filter, one should be aware of the ringing artifact that can be reduced by extrapolating a tail part beyond the cut-off frequency of the filter.
