title: Tensorflow object detection API minimum score threshold
body: <p>I'm running detection with the Tensorflow Object Detection API with the default model and I'd just like to print the detection scores to the console.</p>
  
  <p>For example <code>object_detection_tutorial.ipynb</code> has a function called <code>visualize_boxes_and_labels_on_image_array</code> that draws bounding boxes on the image. This function has a parameter <code>min_score_thresh=.5</code> and if you change it it draws bounding boxes for everything above that threshold.</p>
  
  <p>i'm not visualizing the images though, just want to print out the score for anything > <code>0.2</code> but I can't find a way to specify this?</p>
  
  <p>Currently it's only printing to the console detections with scores above <code>.5</code> which i guess is the default?</p>
