EyeLipCropper

EyeLipCropper is a Python tool to crop eyes and mouth ROIs of the given video. The whole process consists of three parts: frame extraction, face alignment, and eye/mouth cropping. The cropped eye/mouth image size can be customized.

Usage

Prerequisites

>>> pip install -r requirements.txt

1. Extract frames of a given video

>>> python frame_extract.py -h
usage: frame_extract.py [-h] [--video-path VIDEO_PATH] [--images-path IMAGES_PATH]

extract frames with opencv

optional arguments:
  -h, --help            show this help message and exit
  --video-path VIDEO_PATH
                        the input video path
  --images-path IMAGES_PATH
                        the output frames path
 
# default for test: this will generate frames of the video in `./test/images`
>>> python frame_extract.py

2. Align faces of the frames, with library face-alignment

>>> python face_align.py -h
usage: face_align.py [-h] [--images-path IMAGES_PATH] [--landmarks-path LANDMARKS_PATH] [--boxes-path BOXES_PATH] [--device DEVICE] [--log-path LOG_PATH]

align faces with `https://github.com/1adrianb/face-alignment`

optional arguments:
  -h, --help            show this help message and exit
  --images-path IMAGES_PATH
                        the input frames path
  --landmarks-path LANDMARKS_PATH
                        the output 68 landmarks path
  --boxes-path BOXES_PATH
                        the output bounding boxes path
  --device DEVICE       cpu or gpu cuda device
  --log-path LOG_PATH   logging when there are no faces detected
  
# default for test: this will generate landmarks and bounding boxes in
# `./test/landmarks` and `./test/boxes`
>>> python face_align.py

3. Crop left eye, right eye, mouth ROIs, with code modified from processing tools of [Eye] RT-GENE and [Mouth] LipForensics

>>> python eye_mouth_crop.py -h
usage: eye_mouth_crop.py [-h] [--images-path IMAGES_PATH] [--landmarks-path LANDMARKS_PATH] [--boxes-path BOXES_PATH] [--eye-width EYE_WIDTH] [--eye-height EYE_HEIGHT]
                         [--face-roi-width FACE_ROI_WIDTH] [--face-roi-height FACE_ROI_HEIGHT] [--left-eye-path LEFT_EYE_PATH] [--right-eye-path RIGHT_EYE_PATH]
                         [--mean-face MEAN_FACE] [--mouth-width MOUTH_WIDTH] [--mouth-height MOUTH_HEIGHT] [--start-idx START_IDX] [--stop-idx STOP_IDX]
                         [--window-margin WINDOW_MARGIN] [--mouth-path MOUTH_PATH]

crop eye and mouth regions

optional arguments:
  -h, --help            show this help message and exit
  --images-path IMAGES_PATH
                        [COMMON] the input frames path
  --landmarks-path LANDMARKS_PATH
                        [COMMON] the input 68 landmarks path
  --boxes-path BOXES_PATH
                        [EYE] the input bounding boxes path
  --eye-width EYE_WIDTH
                        [EYE] width of cropped eye ROIs
  --eye-height EYE_HEIGHT
                        [EYE] height of cropped eye ROIs
  --face-roi-width FACE_ROI_WIDTH
                        [EYE] maximize this argument until there is a warning message
  --face-roi-height FACE_ROI_HEIGHT
                        [EYE] maximize this argument until there is a warning message
  --left-eye-path LEFT_EYE_PATH
                        [EYE] the output left eye images path
  --right-eye-path RIGHT_EYE_PATH
                        [EYE] the output right eye images path
  --mean-face MEAN_FACE
                        [MOUTH] mean face pathname
  --mouth-width MOUTH_WIDTH
                        [MOUTH] width of cropped mouth ROIs
  --mouth-height MOUTH_HEIGHT
                        [MOUTH] height of cropped mouth ROIs
  --start-idx START_IDX
                        [MOUTH] start of landmark index for mouth
  --stop-idx STOP_IDX   [MOUTH] end of landmark index for mouth
  --window-margin WINDOW_MARGIN
                        [MOUTH] window margin for smoothed_landmarks
  --mouth-path MOUTH_PATH
                        [MOUTH] the output mouth images path

# default for test: this will generate the final cropped left eye,
# right eye, and mouth images in `./test/left_eye`, `./test/right_eye`
# , and `./test/mouth`
>>> python eye_mouth_crop.py
  • Note that the argument --face-roi-width and --face-roi-height should be maximized until there is a printed warning.
