This is an OpenGL program written to create 2D image morphing. Image morphing is usually used to create special effects in movies so that we can see a smooth change from one image to another.

The algorithm is a feature-based image morphing algorithm as described by Beier and Neely at SIGGRAPH 1992. The official website of the paper is available online. Please visit the website to find out more about it.

In this example, an image of a cat is morphed to a dog (and back) smoothly.

Users are required to define pairs of tracking regions manually. The blue highlighted lines below show a pair of such tracking lines.
