The Beier-Neely morphing algorithm is a computer process that takes two different images and makes them gradually change into each other. It works by identifying corresponding points in each image, like a nose or an eye, and moving those points closer together or further apart.
Imagine you have two pictures of yourself, one where you're smiling and one where you're not. The algorithm would find your nose, mouth, and eyes in both pictures and then slowly move the features in the non-smiling picture to match your smiling picture until they blend together smoothly.
This algorithm is often used in animation and graphics to create transformations between shapes and objects without having to create individual frames for each step of the transformation. It saves time and makes the process more efficient.
So, just like a magic trick, the Beier-Neely morphing algorithm uses computer magic to make two different images blend together into one smooth transformation.
