i am new in open cv. im trying to save the detected object into a new image.what will i do : import cv2
import numpy as np
tric_cascade = cv2.CascadeClassifier('cascade.xml')

img = cv2.imread('anthon18c.png')
gray= cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)

tric = tric_cascade.detectMultiScale(gray,1.01,7)
for (x,y,w,h) in tric:
    img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)


cv2.imshow('img', img)
cv2.waitKey(0)
cv2.destroyAllWindows()

this is the code I copied from a tutorial.
