The purpose of this project was to explore the image blending via correspondence points.
I took two pictures of myself, and defined a set of 60 corresponding points. I used the midpoints to create a triangularization, the result of which is shown below.

For each triangle of each frame, I compute the affine transformation matrices to map included points to the source images. Point shift and crossfade progress linearly.

|
|
Final product: 675x900, 45 frames. The execution of this un-optimized code is proportional to the product of width, height, frames, and correspondence points. Each frame took a few minutes to compute, but multiprocessing made computation very manageable.

This was created by subtracting a multiple of the difference between my own face and the mean of the first face type from above.
