摘要:
在介绍脊波理论的基础上,采用平行束投影(Radon变换)加整数小波变换的方法来实现脊波变换,以此为基础设计出一种压缩方案,并将其应用到动态心脏超声波序列图像的压缩中。由于平行束投影对噪声具有抑制作用,整数小波变换可以节约系数的存储空间,因此在相同的压缩环境下,与直接用2-D整数小波变换进行压缩相比,文中的方法能得到更大的压缩比。编码脊波系数时,提出按投影分度方向来组织和预测脊波系数的思想,使得该方法在实现嵌入式编码的同时还具有了较强的鲁棒性。文中的方法可用于远程医疗、CT、MRI和视频压缩等领域
Abstract:
In this paper,on the basis of the theory of the ridgelet, the ridgelet transform which was applied to compress dynamic serial echocardiographic images, implemented by combining parallel projection and integer wavelet transform, Because of parallel projection owning the ability of restraining noise, integer wavelet transform could saving the storage space, under the same compression background, our method had a higher compression ratio than using the 2 - D integer wavelet transform directly. Wlth the idea of organizing and forecasting ridgelet coefficients according to projection direction, the coding stream is fit for gradual transmission and displaying besides strong robustness, Our method can be used for telemedicine, CT, MRI, video coding and so on
