  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
