对于Java,你可以试试这段代码。
private void Harris(Mat Scene, Mat Object, int thresh) {
// This function implements the Harris Corner detection. The corners at intensity > thresh
// are drawn.
Mat Harris_scene = new Mat();
Mat Harris_object = new Mat();
Mat harris_scene_norm = new Mat(), harris_object_norm = new Mat(), harris_scene_scaled = new Mat(), harris_object_scaled = new Mat();
int blockSize = 9;
int apertureSize = 5;
double k = 0.1;
Imgproc.cornerHarris(Scene, Harris_scene,blockSize, apertureSize,k);
Imgproc.cornerHarris(Object, Harris_object, blockSize,apertureSize,k);
Core.normalize(Harris_scene, harris_scene_norm, 0, 255, Core.NORM_MINMAX, CvType.CV_32FC1, new Mat());
Core.normalize(Harris_object, harris_object_norm, 0, 255, Core.NORM_MINMAX, CvType.CV_32FC1, new Mat());
Core.convertScaleAbs(harris_scene_norm, harris_scene_scaled);
Core.convertScaleAbs(harris_object_norm, harris_object_scaled);
for(int j = 0; j < harris_scene_norm.rows() ; j++){
for(int i = 0; i < harris_scene_norm.cols(); i++){
if ((int) harris_scene_norm.get(j,i)[0] > thresh){
Imgproc.circle(harris_scene_scaled, new Point(i,j), 5 , new Scalar(0), 2 ,8 , 0);
}
}
}
for(int j = 0; j < harris_object_norm.rows() ; j++){
for(int i = 0; i < harris_object_norm.cols(); i++){
if ((int) harris_object_norm.get(j,i)[0] > thresh){
Imgproc.circle(harris_object_scaled, new Point(i,j), 5 , new Scalar(0), 2 ,8 , 0);
}
}
}
}
我刚才写的下面的代码here
接受的答案,如果它可以帮助你!这也有助于其他人! –
我试过上面的代码通过了哈里斯(mat,mat,1)作为方法的参数。当我检查图像时,它没有显示任何显示角的圆圈 –
@SivaKReddyCShiva为什么你会传递1? –
