have thes 3 defcfuns, for OpenCV functions (C++) which have been wrapped in C(C and C+++ function definitions have been included), the top 2,%brisk and surf0 can both can be used as the (self feature-detector) param in the bottom one, %feat-detect-detect. If the output of the top two and the self param of feat-detect-detect are just :pointer, But I need to have all three of their types defined similiarly to the (four type functions) on the bottom of the page so I can use finalizers. 



All of the finalizers and types for the three are the same, just substitute in brisk and surf for feature-detector in the four functions at the bottom of the page and you will know what each looks like. 


 Should I just call the types for the output of brisk and surf and the input type of feat-detect-detect by the same name, and make them all use the same 4 function 
type/finalizer combo at the bottom of the page, or is there a better way.
