# lbpcascade_animeface

The face detector for anime/manga using OpenCV.

Original release since 2011 at [OpenCVによるアニメ顔検出ならlbpcascade_animeface.xml](http://ultraist.hatenablog.com/entry/20110718/1310965532) (in Japanese)

## Usage

Download and place the cascade file into your project directory.

    wget https://raw.githubusercontent.com/nagadomi/lbpcascade_animeface/master/lbpcascade_animeface.xml

### Python Example

```python

import cv2

import sys

import os.path

def detect(filename, cascade_file = "../lbpcascade_animeface.xml"):

    if not os.path.isfile(cascade_file):

        raise RuntimeError("%s: not found" % cascade_file)

    cascade = cv2.CascadeClassifier(cascade_file)

    image = cv2.imread(filename, cv2.IMREAD_COLOR)

    gray = cv2.cvtColor(image, cv2.COLOR_BGR2GRAY)

    gray = cv2.equalizeHist(gray)

    

    faces = cascade.detectMultiScale(gray,

                                     # detector options

                                     scaleFactor = 1.1,

                                     minNeighbors = 5,

                                     minSize = (24, 24))

    for (x, y, w, h) in faces:

        cv2.rectangle(image, (x, y), (x + w, y + h), (0, 0, 255), 2)

    cv2.imshow("AnimeFaceDetect", image)

    cv2.waitKey(0)

    cv2.imwrite("out.png", image)

if len(sys.argv) != 2:

    sys.stderr.write("usage: detect.py \n")

    sys.exit(-1)

    

detect(sys.argv[1])

```

Run

    python detect.py imas.jpg

## Note

I am providing similar project at https://github.com/nagadomi/animeface-2009. animeface-2009 is my original work that was made before libcascade_animeface. The detection accuracy is higher than this project. However, installation of that is a bit complicated. Also I am providing a face cropping script using animeface-2009.
