利用OpenCV实现局部动态阈值分割，参考Halcon dyn_threshold算子的思路实现。
#include "dialog.h"#include <QApplication>#include "cv.h"#include "highgui.h"#include <QDebug>int main(int argc, char *argv[]){
IplImage *img = cvLoadImage("D:/cs/1227/f9.bmp",0);
IplImage *out = cvCreateImage(cvGetSize(img),img->depth,1);
cvSmooth(img,out,CV_BLUR,50);
IplImage *res = cvCreateImage(cvGetSize(img),img->depth,1);
qDebug()<<img->nChannels;
double a = 0;
double b = 0;
for(int i=0;
i<img->height;
i++){
for(int j=0;
j<img->width;
j++){
CvScalar color = cvGet2D(img,i,j);
CvScalar color1 = cvGet2D(out,i,j);
a = color.val[0];
b = color1.val[0];
//a = exp(a);
CvScalar c = cvScalar(b-a+128);
cvSet2D(res,i,j,c);
}
}
cvThreshold(res,res,150,255,CV_THRESH_BINARY_INV);
cvNamedWindow("Image",0);
cvShowImage("Image",res);
cvSaveImage("D:/cs/cs.bmp",out);
cvWaitKey(0);
cvReleaseImage(&img);
cvDestroyWindow("Image");
return 0;
}
