title: how to reduce usage aws rekogniton api usage
body: <p>I have created some application that uses aws rekognition service,</p>
  <p>I am doing this via boto3 python library</p>
  <p>here is sample code</p>
  <pre><code>try:
      aws_res = rek_client.search_faces_by_image(CollectionId='inspact',
                                                  Image={
                                                    'Bytes': image_base64},
                                                     MaxFaces=1,
                                                     FaceMatchThreshold=95,
                                                     QualityFilter='HIGH'
                                                     )
  
  except IndexError as e:
          print(e)
          error = 'Unknown face'
          return make_response(error, 400)
  </code></pre>
  <p>I  suspect that API usage that I log in python and face API usage on aws never matches at all ,there is always 30-40% difference, so my question is there anything in code that I'm missing that I have to wrap to make it efficient</p>
