| 摘 要： | 寻求满足检测要求的图像压缩方法是^60Co集装箱检测系统(TC-SCAN)需要解决的一个问题。文章采用了基于小波变换的压缩方法，分析了小波变换后辐射图像灰度的分布特征，并据此设计了最优量化方案，用嵌入式零树编码和自适应算术编码对量化后数据进行编码，实现了辐射图像的有损压缩。

| Abstract: | Its a pending problem for the 60Co container inspection system(TC-SCAN) to find an image compression method that meets systems need. In this article, a method based on wavelet transform is presented. At first, ite analyzes the distributing trait of the transformed image, then an adaptive quantization algorithm is put forward. After that, the quantized data are encoded via embedded zerotree wavelet(EZW)encoder, following the adaptive arithmetic encoder. the lossy compression scheme is realized. |
