so i have this code for my project import cv$2$

import numpy as np

# Initialize the camera

break

while True:

if not ret:

break

motion$\_$contours $=$ detect$\_$motion$($frame$)$

if selected$\_$object is not None:

if alarm$\_$triggered:

print$("$ALARM$!$ Object touched!"$)$

cv$2.$imshow$(\text{'}$Frame$\text{'},$ frame$)$

# Exit the loop on $\text{'}$q$\text{'}$ key press

if cv$2.$waitKey$(30)$ & $0$xFF $==$ ord$(\text{'}$q$\text{'})$:

break

# Cleanup resources

cap.release$()$

cv$2.$destroyAllWindows$()$

what i need is an adjusted version of these code which detects rectangle objects edges instead of circles i still want to detect it by clicking with mouse everything should stay same but i want rectangle object as selected object not a circle
