Stream pedestrian detection web server

Requirements

python = 3.7
redis
flask
opencv
pytorch
dotenv

Please note that you need to install redis on your system.

The architecture.

1 - RealTimeTracking reads frames from rtsp link using threads (Using threads make the web server robust against network packet loss)

2 - In RealTimeTracking.run function in each iteration frame is stored in redis cache on server.

3 - Now we can serve the frames on redis to clients.

4 - To start the pedestrian detection, after running rtsp_webserver.py, send a GET request on 127.0.0.1:8888/run with setting these GET method parameters

Param	Value	Description
run	1/0	to start the tracking set 1/ to stop tracking service set it as 0
camera_stream	'rtsp://ip:port/admin...'	provide it with valid rtsp link

for example:

(to start the service)  127.0.0.1:8888/run?run=1
(to stop the service)  127.0.0.1:8888/run?run=0
(to change the camera) 
    1- 127.0.0.1:8888/run?run=0 (first stop the current service)
    2- 127.0.0.1:8888/run?run=0&camera_stream=rtsp://ip:port/admin... (then start it with another rtsp link)

5 - get pedestrian detection stream in 127.0.0.1:8888
