1. FACE MORPHER alyssaquek alyssaq/face_morpher FOSS Asia 2015
2. Questions to answer Given 2 or more images, how do we create a: • Morph sequence? • Average face? Just 4 steps!
3. Step 1: Locator OpenCV haar cascade classifiers
 face, eye detection Stasm shape models
 key face points
4. Step 2: Aligner Resize; Center face; Pad borders; Crop
5. Step 3: Warper Triangulate points
 (Delaunay triangulation) scipy.spatial.Delaunay(points)
6. Step 3: Warper [a b c d e f ] 2 x 3 
 affine transformation matrix +
 bilinear interpolation
7. Step 4: Morph! Start Mesh End Mesh Many intermediate meshes
8. python morpher.py --src=spock.jpg --dest=uhura.jpg --out_video=out.avi --num=60 --fps=30 Demo Morph!
9. python morpher.py --num=8 --plot --src=star_wars/padme.jpg --dest=star_trek/uhura.jpg Plot as many morph frames
