Do you mean something like this

 Imgproc.findContours(temp, contours, new Mat(),Imgproc.RETR_LIST,Imgproc.CHAIN_APPROX_NONE);

     for(int i =0;i<contours.size();i++)
     {
         // do something 
     }

you are right but I would to Iterate over the contours to remove some contours

You can for example ignore some based on their area

if(Imgproc.contourArea(contours.get(i))>max) { // add bigger contours to new list }
