Detect face then autocrop pictures

Question

I am trying to find an app that can detect faces in my pictures, make the detected face centered and crop 720 x 720 pixels of the picture. It is rather very time consuming &

Answer 1

Just adding to @Israel Abebe's version. If you add a counter before image extension the algorithm will give all the faces detected. Attaching the code, same as Israel Abebe's. Just adding a counter and accepting the cascade file as an argument. The algorithm works beautifully! Thanks @Israel Abebe for this!

import cv2
import os
import sys

def facecrop(image):
facedata = sys.argv[1]
cascade = cv2.CascadeClassifier(facedata)

img = cv2.imread(image)

minisize = (img.shape[1],img.shape[0])
miniframe = cv2.resize(img, minisize)

faces = cascade.detectMultiScale(miniframe)
counter = 0
for f in faces:
    x, y, w, h = [ v for v in f ]
    cv2.rectangle(img, (x,y), (x+w,y+h), (255,255,255))

    sub_face = img[y:y+h, x:x+w]
    fname, ext = os.path.splitext(image)
    cv2.imwrite(fname+"_cropped_"+str(counter)+ext, sub_face)
    counter += 1
return

facecrop("Face_detect_1.jpg")
