How to Use

Users can use the following command to get usage:

>> python main.py -h
usage: main.py [-h] --background_img_path BACKGROUND_IMG_PATH --img_db_path IMG_DB_PATH
               --output_img_path OUTPUT_IMG_PATH --output_xray_path OUTPUT_XRAY_PATH

optional arguments:
  -h, --help            show this help message and exit
  --background_img_path BACKGROUND_IMG_PATH, -b BACKGROUND_IMG_PATH
                        background images floder path
  --img_db_path IMG_DB_PATH, -i IMG_DB_PATH
                        image database for key-points-nearest-search
  --output_img_path OUTPUT_IMG_PATH, -oi OUTPUT_IMG_PATH
                        output blended image folder path to store output
  --output_xray_path OUTPUT_XRAY_PATH, -ox OUTPUT_XRAY_PATH
                        output x-ray folder path to store output

• --background_img_path: the background images database searched by our algorithm.
• --img_db_path: target face images.
• --output_img_path: output path of the generated face image.
• --output_xray_path: output path of the generated face x-ray.

An example can be as follows:

python main.py --background_img_path=./background_img --img_db_path=./img_db --output_img_path=./output --output_xray_path=./output_xray

Structure

get_face_alignment.py

Get the face landmarks of people images.

nearest_search.py

Use nearest search of face landmarks to get the target image face.

generator.py

The main class to generate face X-ray.

utils.py
