title: OpenCV Sample - color-blob-detection
body: <p>The sample project that is available with openCV SDK named <a href="https://github.com/Itseez/opencv/tree/master/samples/android/color-blob-detection" rel="nofollow">"OpenCV Sample - color-blob-detection"</a> identifies the area according to the color of the object you select. It then draws contours around that object. It is possible to extract/highlight that particular area? Since there may also be some other object in the background with the same color, however that is not my desired object.</p>
  
  <p>I know this maybe tricky and involves lot of processing, but some guidance on this will help. How can this be achieved?</p>
  
  <p><strong>Note :-</strong>
  The reason I am asking this, is later we want to model a temporary 3D object on the selected real time object. So differentiating it from the background objects is necessary. </p>
