1. Image Morphing using mesh warp and feature based warp
Choi, Wook-jin

2. Two Dimensional Object Warping

3. Image Morphing

4. Mesh Warping Identify control points for each picture
Place them in mesh matrices
Iterate through each intermediary frame
Find intermediary mesh for each frame
Get the color mappings for this new mesh from each picture
Do a weighted average of the 2 new pictures formed
That is the new image for this intermediary frame

6. Mesh Warp Morphing

7. Feature-Based Warping
Want to use just a set of features
Rather than complete grid
Feature = line drawn on the image
Form intermediate feature image
Simple interpolation of features
Center/orientation or endpoints
Map each pixel to each interpolated feature
Compute associated weight
