新手来了 我正在使用 OpenCV 创建面部识别程序,但出现语法错误,无法确定发生的原因
import cv2
face_cascade = cv2.CascadeClassifier("D:\\Python\\Pycharm Projects\\haarcascade_frontalface_default.xml")
img = cv2.imread("E:\\pic\\Cam\\py.jpg")
gray_img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
faces = face_cascade.detectMultiScale(gray_img, scaleFactor_=_1, minNeighbors=5)
print(type(faces))
print(faces)
for x, y, w, h in faces:
img = cv2.rectangle(img, (int(img, (x,y), (x+w, y+h), (0, 255, 0), 3)
resized = cv2.resize(img, (int(img.shape[1]/2), int(img.shape[0]/2)))
cv2.imshow("Gray", resized)
cv2.waitkey(0)
cv2.destroyAllWindows()
我得到的错误是
File "C:/Users/Areeb Irfan/.PyCharmCE2018.3/config/scratches/facialdetect.py", line 14
resized = cv2.resize(img, (int(img.shape[1]/2), int(img.shape[0]/2)))
^
