title: AWS Rekognition - create image from detect-faces bounding box
body: <p>Currently trying to figure out how to make face crops from bounding boxes (from detect-faces response) and use those crops to search an existing collection using the SearchFacesByImage API</p>
  
  <p>This is mentioned on the SearchFacesByImage documentation.</p>
  
  <blockquote>
    <p>You can also call the DetectFaces operation and use the bounding boxes in the response to make face crops, which then you can pass in to theSearchFacesByImage operation </p>
  </blockquote>
  
  <p>I am trying to do this in Python or Node.js in a Lambda function. The input image is an s3 object.</p>
  
  <p>All help greatly appreciated.</p>
