| Massachusetts General Hospital: no clinically significant image degradation was identified in radiology images up to 30:1 |
| wavelet-based compression technology is superior to all other compression technologies (keeps details, high compression ratio) |
| from a signal processing standpoint, one may view the image as a signal that has high-frequency (high-spatial detail) and low-frequency (smooth) components.The algorithm filters the signal and then iterates the process. |
