Background Subtraction based Drone detections.

Background Subtraction is used to get candidate regions where drones can be. Cascade Classifier is used to detect drone in those region.

Steps to use.

1. main.cpp - takes video input and using background subtraction gets candidate drone region. Background Subtraction Library can be found here - https://github.com/andrewssobral/bgslibrary . Follow the instructions to install it.
2. preprocess_train.cpp - to prepare data to train cascade classifier. OpenCV Cascade Training followed using

opencv_traincascade

Followed instruction from https://docs.opencv.org/2.4.13.2/doc/user_guide/ug_traincascade.html

3. run_classifier.cpp - detect the drones on frames after background subtraction. Cascade Classifier trained by preprocess_train.cpp.
