我正在 javacv 上开发项目,我需要知道如何识别以下图像并使用特定颜色填充该图像?
我尝试解决这个问题,这是我使用的图像
我尝试浏览这段代码,并在 javacv 中开发了一个代码
import com.googlecode.javacpp.Loader;
import com.googlecode.javacv.CanvasFrame;
import static com.googlecode.javacpp.Loader.*;
import static com.googlecode.javacv.cpp.opencv_core.*;
import static com.googlecode.javacv.cpp.opencv_highgui.*;
import static com.googlecode.javacv.cpp.opencv_imgproc.*;
import java.io.File;
import javax.swing.JFileChooser;
public class PolyGonIdentification {
public static void main(String[] args) {
CanvasFrame cnvs=new CanvasFrame("Polygon");
cnvs.setDefaultCloseOperation(javax.swing.JFrame.EXIT_ON_CLOSE);
CvMemStorage storage=CvMemStorage.create();
CvSeq squares = new CvContour();
squares = cvCreateSeq(0, sizeof(CvContour.class), sizeof(CvSeq.class), storage);
JFileChooser f=new JFileChooser();
int result=f.showOpenDialog(f);//show dialog box to choose files
File myfile=null;
String path="";
if(result==0){
myfile=f.getSelectedFile();//selected file taken to myfile
path=myfile.getAbsolutePath();//get the path of the file
}
IplImage src = cvLoadImage(path);//hear path is actual path to image
IplImage gry=cvCreateImage(cvGetSize(src),IPL_DEPTH_8U,1);
cvCvtColor(src, gry, CV_BGR2GRAY);
cvThreshold(gry, gry, 230, 255, CV_THRESH_BINARY_INV);
cvFindContours(gry, storage, squares, Loader.sizeof(CvContour.class), CV_RETR_LIST, CV_CHAIN_APPROX_SIMPLE);
System.out.println(squares.total());
for (int i=0; i<squares.total(); i++)
{
cvDrawContours(gry, squares, CvScalar.ONE, CvScalar.ONE, 127, 1, 8);
}
IplConvKernel mat=cvCreateStructuringElementEx(7, 7, 3, 3, CV_SHAPE_RECT, null);
cvDilate(gry, gry, mat, CV_C);
cvErode(gry, gry, mat, CV_C);
cnvs.showImage(gry);
}
}
我的最终结果应该是这样的图像
上面的代码产生了这种图像。请问有人可以帮我解决这个问题吗?
