Performance analysis of medical image compression techniques with respect to the quality of compression

摘要

In this paper a qualitative analysis of different types of medical image compression techniques have been made. We find that lossless techniques are not much feasible for large data compression while the lossy compression techniques can compress a huge amount of data selectively to improve the over all compression ratio with a good quality factor. The emphasis is done on the recent trends of compression. The wavelet transform based techniques have shown better results in comparison to DCT based techniques (JPEG) due to manifold properties of Wavelet Transform over DCT. The results of the above techniques have been compared and qualitative analysis is done on the basis of compression ratio & quality for medical images.
