Face Smoothing: Detection and Beautification

Input Image	Output Image w/ Facial Smoothing

OpenCV implementation of facial smoothing. Facial detection is done using an pretrained TensorFlow face detection model. Facial smoothing is accomplished using the following steps:

• Change image from BGR to HSV colorspace
• Create mask of HSV image
• Apply a bilateral filter to the Region of Interest
• Apply filtered ROI back to original image

Install

git clone https://github.com/5starkarma/face-smoothing.git
cd face-smoothing

Run

python3 infer.py --input 'path/to/input_file.jpg' (Input file - image, video, or folder with images and/or videos - default is hillary_clinton.jpg)
                         'can/handle/videos.mp4'
                         'as/well/as/directories'
                 --output 'path/to/output_folder' (Output folder - default is data/output)
                 --save_steps 'path/to/file.jpg' (Concats images from each step of the process and saves them)
                 --show-detections (Saves bounding box detections to output)

Example: --save-steps flag
