Hi.
I implemented the algorithm and the result is very good . for example
code:
public Point centerHand(final List<Point> points,final MatOfPoint contour) {
ExecutorService executor = Executors.newFixedThreadPool(10);
final double[] distance = new double[points.size()];
for(int j=0; j<distance.length;j++) {
final int i = j;
executor.execute(new Runnable() {
@Override
public void run() {
distance[i] = findMinDistance(contour.toList(), points.get(i));
}
});
}
executor.shutdown();
executor.awaitTermination(Long.MAX_VALUE, TimeUnit.DAYS);
int maxIndex = -1;
double maxDistance = 0;
for (int index = 0; index < distance.length; index++)
{
if (distance[index] > maxDistance)
{
maxDistance = distance[index];
maxIndex = index;
}
}
Core.circle(image, points.get(maxIndex), (int)maxDistance, new Scalar(0,0,255));
return points.get(maxIndex);
}
private double findMinDistance(List<Point> contourPoints, Point candidate)
{
double result = Double.MAX_VALUE;
for(Point p : contourPoints)
{
result = Math.min(lenght(p, candidate), result);
}
return result;
}
Unfortunately this algorithm is brutal and it works very slowly. How can I do the same thing but faster?
