我正在开发关于
javacv的项目,我需要知道如何识别下面的图像并用特定的颜色填充图像?
我尝试通过这个question,这是我使用的图像 我尝试通过这段代码,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,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,CvScalar.ONE,127,1,8); } IplConvKernel mat=cvCreateStructuringElementEx(7,7,3,CV_SHAPE_RECT,null); cvDilate(gry,mat,CV_C); cvErode(gry,CV_C); cnvs.showImage(gry); } } 我的最终结果应该像这张图片 上面的代码产生了这种形象.有人可以帮我解决这个问题吗? 解决方法
您可以使用此代码对其进行归档
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 Ishape { 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,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),1); cvCvtColor(src,CV_BGR2GRAY); cvThreshold(gry,CV_THRESH_BINARY_INV); cvFindContours(gry,CV_RETR_EXTERNAL,CV_CHAIN_APPROX_SIMPLE); CvSeq ss=null; for (int i=0; i<1; i++) { cvDrawContours(gry,CvScalar.WHITE,CV_RGB(248,18,18),-1,8); ss=cvApproxPoly(squares,CV_POLY_APPROX_DP,8,0); } IplConvKernel mat=cvCreateStructuringElementEx(7,null); cvDilate(gry,CV_C); cvErode(gry,CV_C); cnvs.showImage(gry); } } 结果 这将是结果,我相信这可以帮助您解决您的问题.
