Hello,

I haven't worked that much with openCV in python, so can't provide choosing
help right away. But searched on Google for similar topic and found the
following link:

http://stackoverflow.com/questions/13211745/detect-face-then-autocrop-pictures

Hope this helps.

Please ask more specific questions *after* you have tried for
yourself. Did you even try searching Google, e.g., "cv2 crop detected
faces" turns up many likely-looking links.

Hi,
import cv2

def detect(path):
img = cv2.imread(path)
cascade = cv2.CascadeClassifier("haarcascade_frontalface_alt.xml")
rects = cascade.detectMultiScale(img, 1.3, 4,
cv2.cv.CV_HAAR_SCALE_IMAGE, (20,20))

if len(rects) == 0:
return [], img
rects[:, 2:] += rects[:, :2]
return rects, img

def box(rects, img):
for x1, y1, x2, y2 in rects:
cv2.rectangle(img, (x1, y1), (x2, y2), (127, 255, 0), 2)


rects, img = detect("hi.jpg")

cropped = img[70:17, 40:40]
cv2.imshow("cropped", cropped)
cv2.waitKey(0)
box(rects, img)

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

This is a face detection code.This will work properly.but I want to crop
the detected faces and it should display on the screen.

[BangPypers] About code

2014-11-25 Thread narayan naik 
Hi,

import numpy as np
import cv2
img=cv2.imread('4.jpg',0)
cv2.imshow('image',img)
k=cv2.waitKey(0)
if k == 27:
cv2.destroyAllWindows()
#cv2.destroyWindow('image')
elif k == ord('S'):
cv2.imwrite('image.png',img)
cv2.destroyAllWindows()

when I run this code,it is not possible to close the image window by
pressing esc key,and if going to close by using mouse the window will hang.
