You can see there is no detect rectangle. Where is wrong?

Thanks!

Below is my codes:

import numpy as np import cv2

face_cascade = cv2.CascadeClassifier('haarcascade_frontalface_default.xml') eye_cascade = cv2.CascadeClassifier('haarcascade_eye.xml')

img = cv2.imread('./nbaplayer/203500.png') print img.shape print img.size gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY) hsv = cv2.cvtColor(img, cv2.COLOR_BGR2HSV)

print gray.shape

print gray.size

cv2.imshow('img1',gray)

cv2.imshow('hsv',hsv) faces = face_cascade.detectMultiScale(gray,2,1) print faces for (x,y,w,h) in faces: img = 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.rectangle(img,(38,0),(23,128),(255,255,255),3)

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