Dlib中imglab生成失败的解决方法

2018-11-19 2018-11-19 view times

PS：花了一个晚上才把imglab这个标注工具生成失败的问题解决，哎，我真的太木了

1.问题所在

dlib\image_saver 下的头文件 save_png.h 出现 Assertion Failed
可以看到作者在 #ifndef DLIB_PNG_SUPPORT 下其实打了超多感叹号的注释

You are getting this error because you are trying to use save_png() but you haven't defined DLIB_PNG_SUPPORT.  You must do so to use this function. You must also make sure you set your build environment to link against the libpng library.

2.解决方法

解决方法很简单，我开始还在研究是不是要配置第三方库libpng和zlib的环境
其实只要在imglab主函数里声明
#define DLIB_PNG_SUPPORT 和 #define DLIB_JPEG_SUPPORT
