Can anyone help me to understand this?
public static int getBiggestContourIndex(List<MatOfPoint> contours){
double maxArea = 0;
Iterator<MatOfPoint> each = contours.iterator();
int j = 0;
int k = -1;
while (each.hasNext())
{
MatOfPoint wrapper = each.next();
double area = Imgproc.contourArea(wrapper);
if (area > maxArea){
maxArea = area;
k = j;
}
j++;
}
return k;
}Basically like @berak suggested you not reading your code. The following line selects the largest blob.
int k = getBiggestContourIndex(contours);If yoy want to detect all blobs, get amount of elements from contour vector, then iterate over it using a for loop and do processing for each blob in the loop.
Do you mean, i should make a new "get center point" with different point?
You can get the amount of elements of the contour vector by using it size property. Then do a for loop and visualize each blob with the same code like above. If you do not understand it, then it isn't a problem of computer vision, but about not understanding the basics of C++ programming.
thank you, i'm trying :)

oh dear, can't read your own code ?
probably just a copy paste ;)
Can you explain why you keep editing the question if it is already solved?
