摘要
针对连续多帧的DICOM图像 ,本文借鉴了基于DCT变换的视频压缩编码方法 ,提出了采用先进行运动估计和运动补偿 ,然后再对误差帧进行小波变换的视频处理的参考方法。实验结果表明该算法产生的压缩比能够稳定在20以上 ,峰值信噪比都在30db以上。另外本文采用了改进三步搜索法 ,提高了编码效率。能够很好地满足医疗图像序列压缩和传输的要求。
For multi-frame continuous DICOM images,this paper consults the DCT-based coding method of video compression,a new method is put forward that uses wavelet transform on error-frame after motion estimation and motion compensation.Experiment results indicate that the compression ratio of the above method can be stably above20and Peak-Value SNR(Signal-Noise-Ratio)can be above30db.And this paper also adopts an improved TSS which can improve the coding efficiency.So the method can meet the compression and transmission requests of medical image array very well.
