在Python中捕获双眼opencv

Question

我想从图像中检测双眼，但是当我使用Haar级联时，它会分别返回每只眼睛。我应该怎么做才能从图像中剔除双眼？ 这里是我的代码：

image = cv2.imread('KA.AN1.39.tiff') 
eye_cascade = cv2.CascadeClassifier('haarcascade_eye.xml') 
eye = eye_cascade.detectMultiScale(image) 
for (x,y,w,h) in eye: 
    eye = image[y : y+h , x : x+w] 
    cv2.imshow('eye', eye) 
    cv2.waitKey(0) 
    cv2.destroyAllWindows() 

感谢您的帮助

Answer 1

for x,y,w,h in eye: 
    roi_gray = gray[y:y+h, x:x+w] 
    roi_color = img[y:y+h, x:x+w] 
    eyes = eyePair_cascade.detectMultiScale(roi_gray) 
    if len(eyes) == 0: return 
    for (ex,ey,ew,eh) in eyes: 
     eyes_roi = roi_color[ey: ey+eh, ex:ex + ew] 
     #cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2) 

cv2.imwrite(outfile, eyes_roi)
