Compression algorithms are widely used in medical image database systems. So far, compressed images have been mainly evaluated by visual assessment on acceptable compression levels in clinical studies. However, to the best of our knowledge, little work has been done to clarify image properties based on physical analysis. In this work, investigations were made to clarify image properties based on physical analysis and to discuss the major causes of degradation related to compression ratios. The physical properties of compressed images performed by JPEG2000 and JPEG in CR were compared by measuring the MTF, NPS, PSNR, and NEQ. |
