Mdlib is used to detect motion on resized image (frame).
At the moment, the installation looks like this :
- By pip install git+https://github.com/noxgle/mdlib.git
- Web browser: mdlib
- Console: wget -O move_detection.py https://lvk.pl/iYnoL-Y
- OpenCV
Checkout test_move_detection.py in test folder.
import cv2
from mdlib import MoveDetection
cap = cv2.VideoCapture(0)
MD = MoveDetection()
while True:
ret, frame = cap.read()
if MD.check(frame) is True:
print('Move detect') All parm are predefined.

Check if motion has been detected.
:param new_frame: image (frame)
:return: True if detected object or False if not
Get the rectangles data of the detected motion for the original image.
:param frame: image (frame)
:return: [[x,y,w,h]] for detected object
Get the one combined rectangle data of the detected motion for the original image.
:param frame: image (frame)
:return: [[x,y,w,h]] for detected object
Get the rectangles data of the detected motion for the resized image.
:return: [[x,y,w,h]] for detected object
Get the one combined rectangle data of the detected motion for the resized image.
:return: [[x,y,w,h]] for detected object
Draw a rectangle in the area where motion has been detected on original frame.
:param frame: original image (frame)
