contours, hierarchy = cv2.findContours(roiImg,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)
for i in contours:
area = cv2.contourArea(i)
moments = cv2.moments (i)
if area>1500:
if moments['m00']!=0.0:
if moments['m01']!=0.0:
cx = int(moments['m10']/moments['m00']) # cx = M10/M00
cy = int(moments['m01']/moments['m00']) # cy = M01/M00
cv2.circle(frame,(cx,cy+350), 4, (255,0,0), -1)
cv2.circle(frame,(cx,cy+350), 8, (0,255,0), 0)
these codes is written by python , but I want to know how to write them in c++
