CS 1430 Project 1: Hybrid Images with Gaussian and Laplacian Pyramids

Overview

Hybrid images are created by adding up the N number of images from the laplacian pyramids to the N+1 entry in the Guassian Pyramid. The Gaussiam pyramid entries store all the low frequencies and the Laplacian entries store all the high ones.


The pyramids

Gaussian on the top followed by Lalpacian. Color map for the laplacian changed to pink for better viewing

Hybrid Images Generated

Hybrid Image 1: Cat or Dog?!



Hybrid Image 2: Einstein or Monroe?!



Hybrid Image 3: Car or Rhino?!



Hybrid Image 3: Obama or Bush?!



Bonus: Color Hybrid Images

Bonus Hybrid Image 1: Colored Cat or Dog?!



Bonus Hybrid Image 2: Colored Cat or Dog?!

Only the dog is in color. The poor car is BLACK and WHITE. Old School. There seems to be not much difference seen here between both images colored vs. only one of them colored. But ideally, it would make sense to use color images for low frequency pictures. Low frequencies have intensity information while high frequency retain edge information. So color would make more sense for low frequency part of the hybrid image
