Image Morphing using mesh warp and feature based warp 20061152 Choi, Wook-jin

Two Dimensional Object Warping

Image Morphing

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

Mesh Warping

Mesh Warp Morphing

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

Feature-Based Warping

Warping with Multiple Line Pairs

Weighting Effect of Each Line Pair

Cross-Dissolving
