title: How to detect if a point is contained within a bounding rect - opecv & python
body: <p>I have a set of points [(x0,y0), (x1,y1), .. ]</p>
  
  <p>And a set of bounding rectangles produced using the <code>cv2.boundingRect(someContour)</code> function.
  Where each bounding box is an iterable object with four coordinates <code>(a,b,c,d)</code>.
  My questions are: </p>
  
  <ol>
  <li><p>what is the meaning of these four numbers?.</p></li>
  <li><p>how to check if each given point is contained within the bounding rect? </p></li>
  </ol>
  
  <p>I know that opencv for C++ has the 'contains' method but it doesnt exist for python. </p>
