示例1: Mat_to_vector_DMatch
import org.opencv.core.DMatch; //导入依赖的package包/类
public static void Mat_to_vector_DMatch(Mat m, List<DMatch> matches) {
if (matches == null)
throw new java.lang.IllegalArgumentException("Output List can't be null");
int count = m.rows();
if (CvType.CV_64FC4 != m.type() || m.cols() != 1)
throw new java.lang.IllegalArgumentException(
"CvType.CV_64FC4 != m.type() || m.cols()!=1\n" + m);
matches.clear();
double[] buff = new double[4 * count];
m.get(0, 0, buff);
for (int i = 0; i < count; i++) {
matches.add(new DMatch((int) buff[4 * i], (int) buff[4 * i + 1], (int) buff[4 * i + 2], (float) buff[4 * i + 3]));
}
}

import org.opencv.core.DMatch; //导入依赖的package包/类
public void fromArray(DMatch...a) {
if(a==null || a.length==0)
return;
int num = a.length;
alloc(num);

buff[_channels*i+2] = m.imgIdx;
buff[_channels*i+3] = m.distance;
}
put(0, 0, buff); //TODO: check ret val!
}
示例3: toArray
