opencv to dll p

try to write some opencv

this is what I ended up with very simple but I can seem to get it to run when called externally - can anyone point to where I might be going wrong - tks M

[code]

include "stdafx.h"

include "opencv2/highgui/highgui.hpp"

include "opencv2/imgproc/imgproc.hpp"

include "opencv2/core/core.hpp"

include <iostream>

include <stdio.h>

using namespace std; using namespace cv;

extern "C" {

_declspec (dllexport) double adaptiveThreshold(unsigned __int8 *Igray, unsigned __int8 *Iat, double fixed_threshold, int adaptive_method, int threshold_type, int block_size, double offset);

} //extern "C"

_declspec (dllexport) double adaptiveThreshold(unsigned __int8 *Igray, unsigned __int8 *Iat, double fixed_threshold, int adaptive_method, int threshold_type, int block_size, double offset) {
// allocate memory for example for Mat // Mat src_baseR(rows,cols,CV_8U,&base_imageR[0]);

fixed_threshold = 255;
threshold_type = 0; //fixed_threshold invert(0=off|1=on)
adaptive_method = 0; //adaptive_type(0=mean|1=gaussian) use gaussion looks interesting  

block_size = 17;
offset = 10;

//Mat Iat;  
// Use the Adaptive method for testing
