执行simpleITK框架进行图像配准时候发生如下错误：

sitk::ERROR: No ImageJ/Fiji application found.

执行命令如下，可以使用不同的变换器。

解决：

注意：fiji软件包的底层环境是java，所以需要提前安装好java哦。

可以再cmd中输入java命令测试，你的系统是否已经安装好了java.

下载fiji软件包：笔者选择windows64位

Fiji Downloads

下载完成之后，解压，会得到一个叫做Fiji.app的文件夹。

将Fiji.app的文件夹拷贝包笔者使用的anaconda主环境的Scripts文件夹中。

D:\anaconda\Scripts\Fiji.app

OK了
