摘要
为解决高速线阵CCD交汇测试系统中数据量大而难以有效存储和传输的问题,设计并实现了基于关注区域提取的弹丸图像压缩方法.该方法结合了弹丸图像压缩特性,将弹丸目标区域作为关注区域进行原始恢复而对关注区域以外的背景区域则采用基于JPEG2000的小波压缩方法.实验结果表明该方法可以保证关注区域信息的完整性和获得较高的压缩比,解决了高速线阵CCD交汇测试系统中大量数据的有效存储和传输.
In order to solve the problems of inefficient storage and transmission resulting from the large data in the high-speed linear CCD Intersectant Testing System, the authors design and accomplish the pill image compression based on the methods of focusing on interested area. This method combines the compression properties of pill images and takes the pill area as the interested area, then givs the pill area complete recovery and process the background area with Wavelet JPEG 2000 compression. The testing results testify that the new method can achieve both the integrity of interested area and the high compression ratio, so it can solve the problems in the high-speed linear CCD interseetant testing system well.
