基于OpenCV进行动漫人物和真人脸部眼睛定位-20200813

参考基于OpenCV与 ImageAI 的动漫人物识别

汇总：

import cv2
import os.path

cascade = cv2.CascadeClassifier('./dir/lbpcascade_animeface.xml')  # 引入xml
filename = 'dldongmanrenwu.png'
image = cv2.imread(filename, cv2.IMREAD_COLOR)  # 读入一幅彩色图片

gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)  # 色彩空间转换
gray = cv2.equalizeHist(gray)  # 图像直方图均衡化

faces = cascade.detectMultiScale(gray,
                                 # detector options
                                 scaleFactor=1.1,
                                 minNeighbors=5,
                                 minSize=(25, 25))

i = 0
print(faces)
for (x, y, w, h) in faces:
    cv2.rectangle(image, (x, y), (x + w, y + h), (0, 0, 255), 2)

    face = image[y: y + h, x:x + w, :]
    face = cv2.resize(face, (96, 96))
    save_filename = '%s_%d.png' % (os.path.basename(filename).split('.')[0], i)
    cv2.imwrite("faces/" + save_filename, face)
    i = i + 1

cv2.imshow("AnimeFaceDetect", image)
cv2.waitKey(0)
cv2.imwrite("out2.png", image)

类似是人脸和眼睛的定位：

import cv2

face_cascade = cv2.CascadeClassifier(r'D:\ProgramData\Anaconda3\envs\duellinks\Lib\site-packages\cv2\data\haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier(r'D:\ProgramData\Anaconda3\envs\duellinks\Lib\site-packages\cv2\data\haarcascade_eye.xml')

#img = cv2.imread(r'C:\Users\\nsquair\PycharmProjects\YugiOhDuelLinks_Bot\\backgroud_1.png')
img = cv2.imread('danren.jpg')
#gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(gray, 1.3, 5)
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.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
