基于ARM9处理器S3C2410和嵌入式linux操作系统,给出了一种JPEG2000图像编码实现方法。阐述了嵌入式Linux硬件系统的搭建和软件开发环境的建立,论述了在宿主机linux下JPEG2000压缩算法的实现,并完成编译、链接后的可执行代码向目标平台的移植。系统实现成本低,实现了可变压缩比的JPEG2000图像压缩、存储与显示,可广泛应用于智能交通、计算机视觉、通信、远程监控等领域。
Based on ARM9 processor S3C2410 and embedded Linux operating system, a method of JPEG2000 image coding is given. The establishment of embedded Linux hardware system and the establishment of software development environment are expounded. The realization of JPEG2000 compression algorithm in host Linux and the transplanting of compiled and linked executable code to the target platform are discussed. The system has the advantages of low cost, JPEG2000 image compression, storage and display of variable compression ratio, which can be widely applied in fields of intelligent transportation, computer vision, communication and remote monitoring.
