Kakadu简介 Kakadu Software is a comprehensive, heavily optimized, fully compliant software toolkit for JPEG2000 developers. It is a complete implementation of the JPEG2000 standard, Part 1, — i.e., ISO/IEC 15444-1. The Software Development Kit (SDK) also provides a comprehensive implementation for several of the most useful features from Part 2 of the JPEG2000 standard, including general multi-component transforms and arbitrary wavelet transform kernels. This image compression standard is substantially more sophisticated than the existing JPEG standard, both from a computational and a conceptual perspective. Kakadu home and download url Kakadu Software | Kakadu Software kakadusoftware.com/downloads/ MSYS2 download URL nchc.dl.sourceforge.net/project/msys2/Base/x86_64/msys2-x86_64-20190524.exe 以下操作步骤，是针对于下载的是Linux版本的kakadu的demo 1、将kakadu的demo放到Linux系统的某个目录下。 2、解压kakadu的demo文件 3、使用 vi /etc/profile 命令 添加如下环境变量 PATH=$PATH:~/kakadu/bin LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/kakadu/bin export PATH export LD_LIBRARY_PATH 4、使用 source /etc/profile 命令，使得前一步配置的环境变量生效果(很重要，也可以重启Linux 使得配置的环境变量生效) 5、进入到kakadu的demo目录下linux压缩，修改可执行文件的权限，使用如下命令 chmod +x * 6、压缩图片，使用如下命令压缩 ./kdu_compress -i lena.bmp -o out.j2c -rate 1.0 7、解压图片，使用如下命令解压 ./kdu_expand -i out.j2c -o abc.bmp （编辑：拼字网 - 核心网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
