Warp, morph and average human faces!

Project Description

Warp, average and morph human faces!
Scripts will automatically detect frontal faces and skip images if none is detected.

Built with Python, OpenCV, Numpy, Scipy, Stasm.

Supported on Python 2.7, Python 3.5+ and OpenCV 3.2, 3.4 on macOS High Sierra and 64bit Linux



Use as local command-line utility

$ git clone

Morphing Faces

Morph from a source to destination image:

python facemorpher/ --src=<src_imgpath> --dest=<dest_imgpath> --plot

Morph through a series of images in a folder:

python facemorpher/ --images=<folder> --out_video=out.avi

All options listed in (pasted below):

Morph from source to destination face or
Morph through all images in a folder

Usage: (--src=<src_path> --dest=<dest_path> | --images=<folder>)
            [--width=<width>] [--height=<height>]
            [--num=<num_frames>] [--fps=<frames_per_second>]
            [--out_frames=<folder>] [--out_video=<filename>]
            [--alpha] [--plot]

  -h, --help              Show this screen.
  --src=<src_imgpath>     Filepath to source image (.jpg, .jpeg, .png)
  --dest=<dest_path>      Filepath to destination image (.jpg, .jpeg, .png)
  --images=<folder>       Folderpath to images
  --width=<width>         Custom width of the images/video [default: 500]
  --height=<height>       Custom height of the images/video [default: 600]
  --num=<num_frames>      Number of morph frames [default: 20]
  --fps=<fps>             Number frames per second for the video [default: 10]
  --out_frames=<folder>   Folder path to save all image frames
  --out_video=<filename>  Filename to save a video
  --alpha                 Flag to save transparent background [default: False]
  --plot                  Flag to plot images [default: False]
  --version               Show version.

Averaging Faces

Average faces from all images in a folder:

python facemorpher/ --images=<images_folder> --out=average.png

All options listed in (pasted below):

Face averager

Usage: --images=<images_folder> [--blur] [--alpha] [--plot]
            [--width=<width>] [--height=<height>] [--out=<filename>]

  -h, --help             Show this screen.
  --images=<folder>      Folder to images (.jpg, .jpeg, .png)
  --blur                 Flag to blur edges of image [default: False]
  --alpha                Flag to save with transparent background [default: False]
  --width=<width>        Custom width of the images/video [default: 500]
  --height=<height>      Custom height of the images/video [default: 600]
  --out=<filename>       Filename to save the average face [default: result.png]
  --destimg=<filename>   Destination face image to overlay average face
  --plot                 Flag to display the average face [default: False]
  --version              Show version.

Steps (facemorpher folder)

1. Locator

  • Locates face points (using stasm)
  • For a different locator, return an array of (x, y) control face points

2. Aligner

  • Align faces by resizing, centering and cropping to given size

3. Warper

  • Given 2 images and its face points, warp one image to the other
  • Triangulates face points
  • Affine transforms each triangle with bilinear interpolation

4a. Morpher

  • Morph between 2 or more images

4b. Averager

  • Average faces from 2 or more images


Optional blending of warped image:

  • Weighted average
  • Alpha feathering
  • Poisson blend

Examples - Being John Malkovich

Create a morphing video between the 2 images:

> python facemorpher/ --src=alyssa.jpg --dest=john_malkovich.jpg

(out.avi played and recorded as gif)

Save the frames to a folder:

> python facemorpher/ --src=alyssa.jpg --dest=john_malkovich.jpg
--out_frames=out_folder --num=30

Plot the frames:

> python facemorpher/ --src=alyssa.jpg --dest=john_malkovich.jpg
--num=12 --plot

Average all face images in a folder:

85 images used

> python facemorpher/ --images=images --blur --alpha
--width=220 --height=250

Use as pip library

$ pip install facemorpher


Additional options are exactly the same as the command line

import facemorpher

# Get a list of image paths in a folder
imgpaths = facemorpher.list_imgpaths('imagefolder')

# To morph, supply an array of face images:
facemorpher.morpher(imgpaths, plot=True)

# To average, supply an array of face images:
facemorpher.averager(['image1.png', 'image2.png'], plot=True)

Once pip installed, 2 binaries are also available as a command line utility:

$ facemorpher --src=<src_imgpath> --dest=<dest_imgpath> --plot
$ faceaverager --images=<images_folder> --plot


  • Data for the haar face classifiers are in the facemorpher/data folder
  • Stasm binary in facemorpher/bin/stasm_util. You can build a new stasm binary with the Stasm 4 build scripts.
