Flask based web application that provides a REST endpoint using OpenCV's Deep Neural Network method for Object Detection
python server.py
If this is run locally, the endpoint is: http://localhost:5000/is_person.
If a person is detected response: {"response": "person likely found"}
Response for everything else: {"response": "no people found"}
To use the endpoint, send a POST request with a JSON blob that looks like this: {"image_path": "your-image-url-here"}.
Libraries: flask, numpy, cv2, requests, os
Since openCV's installation procedure is a little tricky, here is a link which provides scripts to install openCV depending on the OS - https://github.com/jayrambhia/Install-OpenCV
Another useful link - https://www.pyimagesearch.com/2016/10/24/ubuntu-16-04-how-to-install-opencv/
Note that there are a number of dependencies. I'm not sure what the best way is to list these, so if you get the app working, then hooray. This is more about having a reference of how to make a OpenCV DNN based REST endpoint using Flask.
