Image morphing using continuous mode interpolation

Morphing between two distinct images is based on continuous mode interpolation developed for reduced order flow models. First, outer products of input vectors (images) result in two matrices, that are linearly interpolated. Next, eigenvectors of interpolated matrix are computed. Most dominant one is the morphed image we seek.

On the example below, two photos of Pfaueninsel castle are morphed:
