如何解决opencv2 error C4996: 'fopen'

Visual Studio使用opencvc出现以下错误：
\opencv2\flann\logger.h(66):error C4996: 'fopen': This function or variable may be unsafe. Consider usingfopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. Seeonline help for details.
1> c:\program files (x86)\microsoft visual studio12.0\vc\include\stdio.h(211) : see declaration of 'fopen'

解决方法
在属性-->C++-->Preprocessor-->PreprocessorDefinitions里加入 _CRT_SECURE_NO_WARNINGS即可
