This problem set will let you play around with multi-resolution techniques for images.
  1. Implement the Adelson and Burt algorithm for splining overlapping images. The input images can be of any size. This will involve writing programs to compute the Laplacian pyramid for a given color image and the Gaussian pyramid for image masks. Implement Expand and Reduce as the basic routines for constructing the pyramids. You can use a 5x5 kernel with the weights as given in the paper.
  2. Use your program to spline a pair of color images of your choice.
  3. Use your program to form a composite images using combinations of images from http://www-astronomy.mps.ohio-state.edu/~dixie/animals.html OR
  4. Please feel free to gather images from the WWW or collect them via camera or scanner.
  5. For extra credit, compute an additional montage for a sequence of moving video images.
  6. When done, Create an HTML document that gives the matlab program source code and script saved via the diary command and shows your output images.
