Python人脸检测，Windows下

[qq_38989622]

import cv2
import sys

# Get user supplied values
imagePath = sys.argv[1]
cascPath = "haarcascade_frontalface_default.xml"

# Create the haar cascade
faceCascade = cv2.CascadeClassifier(cascPath)

# Read the image
image = cv2.imread(imagePath)
gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

# Detect faces in the image
faces = faceCascade.detectMultiScale(
gray,
scaleFactor=1.1,
minNeighbors=5,
minSize=(30, 30),
flags = cv2.cv.CV_HAAR_SCALE_IMAGE
)

print("Found {0} faces!".format(len(faces)))

# Draw a rectangle around the faces
for (x, y, w, h) in faces:
cv2.rectangle(image, (x, y), (x+w, y+h), (0, 255, 0), 2)

cv2.imshow("Faces found", image)
cv2.waitKey(0)
我在网上找到这段代码运行，但是总是出现这个问题，请问各位大神怎么破

把 imagePath = sys.argv[1] 改一下 imagePath = “你的图片路径”

引用 1 楼 seakingx 的回复:

把 imagePath = sys.argv[1] 改一下

imagePath = “你的图片路径”

我改成这样子之后,又出现了这个问题，可是我的图片是彩色图片

没研究过opencv 直接用image 没有结果吗? faces = face_patterns.detectMultiScale(image ,scaleFactor=1.1,minNeighbors=5,minSize=(100, 100))
