| 摘 要： | 针对牙颌模型深度数据的压缩处理问题,阐述了嵌入零树小波(Embedded Zerotree Wavelet,EZW)编码算法的基本原理和算法实现,讨论了基于感兴趣区域的EZW算法及其实现,并在实验室进行了深度数据和三维重构图像的基于感兴趣区域的EZW编码实验.实验表明,EZW编码既能实现图像的有损压缩也可实现图像的无损压缩,并具有很大的压缩比.

| Abstract: | Compared with other data compression algorithms,the basic principle and algorithm of EZW(that is Embedded Zerotree Wavelet coding) were introduced.EZW algorithm and its realization based on region of interests were discussed.In laboratory condition,EZW coding experiments of 3D cast data and 3D reconstruction image based on region of interests were carried out.And the results indicate that EZW algorithm can realize not only losing image compression but also lossless image compression with high compression ra... |
