A Vision Based Sense and Avoid System for Small UAV's.

main.py -> Video Processing and performing ops in order.

src/horizon.py -> Horizon class for predicting horizon and also keeping track of previousily detected horizons to calculate EMWA.

src/detect.py -> Detect small objects by comparing with previous frames and also by removing False Positives.

src/validation.py -> Used to find the predicted bbox iou with the truth. Run the file to look at the ground truth values.
