   * for training with a large number of objects in each image, add the parameter `max=200` or higher value in the last layer [region] in your cfg-file

   * General rule - you should keep relative size of objects in the Training and Testing datasets the same: 
 
     * `train_network_width * train_obj_width / train_image_width ~= detection_network_width * detection_obj_width / detection_image_width`
