| 摘 要： | 本文提出了一种基于三维小波变换的医学图像压缩编码算法。根据图像经过小波变换以后的系数特征,本文改进了传统的基于块分裂编码算法（SPECK）所使用的原始的零块分裂方式,提出了一种新的零块分裂方法,该方法有效地提高了编码的有损和无损压缩性能。试验结果表明,本文算法的性能优于JPEG2000编码算法。

| Abstract: | An algorithm of medical image compression coding based on 3D wavelet transformation is proposed in this paper.According to the features of transformed data,we improved traditional spilt way of zero blocks,and proposed a new method which effectively improved the performance of loss and lossless compression images.The result showed better function than JPEG2000. |
