what is the rule to check if a macro definition is in cv namespace

asked 2013-04-15 11:36:50 -0500

I found some of the macro definitions in opencv are within the namespace of cv, while others are not. For example, CV_32F is not within cv namespace, but NORM_L2 is.

Could someone tell me what the rule is to determine if a macro definition is within cv namespace or not? Thanks.

most probably anything changed/added since 2.0 is inside the cv namespace, and anything invented before is not. ( so it does not break bw compatibility )

CV_32F is a macro (#define) that can't be under namespace (since v 1.x) NORM_L2 is a enum value that is under namespace cv similar to most of v 2.x stuff.
