PsyTrack: multi face morphing / multi-image morphing

A walkthrough to perform multi-face/multi-image morphing using psytrack.

Step 0 : understand the coordinate system
Step 1 : load all the images
Step 2 : mark essential coordinates
Step 3 : create the target mask
Step 4 : morph all the images
Step 5 : add the images together

A walkthrough on performing the eyetracking itself

Step 0 : import the eye tracking data
Step 1 : normalize the eye tracking coordinates matching the target morph
Step 2 : create the probability distributions
Step 3 : Normalize the probability distribution
Step 4 : overlay the images
Step 5 : export the image

The result on a particular experiment on the eye tracking of sex determination of images (here).
