Hey there guys!
I'm a newbie in python thing. I'm trying to crop the ROI from video stream. But i got no result at the moment. The code i'm using is:
import numpy as np import cv2
face_cascade = cv2.CascadeClassifier('C:\opencv\sources\data\haarcascades\haarcascade_frontalface_default.xml') eye_cascade = cv2.CascadeClassifier('C:\opencv\sources\data\haarcascades\haarcascade_eye.xml')
cap = cv2.VideoCapture(0)
while 1: ret, img = cap.read() gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) faces = face_cascade.detectMultiScale(gray, 1.3, 5)
for (x,y,w,h) in faces:
cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
roi_gray = gray[y:y+h, x:x+w]
roi_color = img[y:y+h, x:x+w]
eyes = eye_cascade.detectMultiScale(roi_gray)
for (ex,ey,ew,eh) in eyes:
cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2)
cv2.imshow('img',img)
k = cv2.waitKey(30) & 0xff
if k == 27:
break
cap.release() cv2.destroyAllWindows()
crop_img = roi_color[?] cv2.imwrite("path", roi_color)
Any advice is welcome! Have a nice day
