如题，对字符图片进行字符分割，采用的外轮廓最小外接矩形的方法，分割效果如图
为什么顺序不是从右到左呀，这样没有顺序的分割没太有意义呀。请问有人知道怎么改成分割后结果顺序从右到左或者从左到右么，谢谢！！！！代码如下
#include "stdafx.h"
#include "cv.h"
#include "highgui.h"
#include "cxcore.h"
int main(int argc, char* argv[])
{
IplImage* imgSrc = cvLoadImage("C:\Users\think\Desktop\腐蚀膨胀结果.jpg",CV_LOAD_IMAGE_COLOR);
IplImage* img_gray = cvCreateImage(cvGetSize(imgSrc), IPL_DEPTH_8U, 1);
cvCvtColor(imgSrc, img_gray, CV_BGR2GRAY);
cvThreshold(img_gray, img_gray,100, 255,CV_THRESH_BINARY);// CV_THRESH_BINARY_INV使得背景为黑色，字符为白色，这样找到的最外层才是字符的最外层
cvShowImage("ThresholdImg",img_gray);
CvSeq* contours = NULL;
CvMemStorage* storage = cvCreateMemStorage(0);
int count = cvFindContours(img_gray, storage, &contours,sizeof(CvContour),CV_RETR_EXTERNAL,CV_CHAIN_APPROX_NONE,cvPoint(0,0));
printf("轮廓个数：%d",count);
int idx = 0;
char szName[56] = {0};
int tempCount=0;
for (CvSeq* c = contours; c != NULL; c = c->h_next)
{
CvRect rc =cvBoundingRect(c,0);
cvDrawRect(imgSrc, cvPoint(rc.x, rc.y), cvPoint(rc.x + rc.width, rc.y + rc.height), CV_RGB(255, 0, 0));
IplImage* imgNo = cvCreateImage(cvSize(rc.width, rc.height), IPL_DEPTH_8U, 3);
cvSetImageROI(imgSrc, rc);
cvCopyImage(imgSrc, imgNo);
cvResetImageROI(imgSrc);
sprintf(szName, "wnd_%d", idx++);
cvNamedWindow(szName);
cvShowImage(szName, imgNo);
cvReleaseImage(&imgNo);
}
cvNamedWindow("src");
cvShowImage("src", imgSrc);
cvWaitKey(0);
cvReleaseMemStorage(&storage);
cvReleaseImage(&imgSrc);
cvReleaseImage(&img_gray);
cvDestroyAllWindows();
return 0;
}
