Project 6: Image Warping and Mosaics

Albert Phone

Part 1: Warping

For the first part, I took a couple photos of posters I own and some parts of Etcheverry Hall. I generally tried to use pictures which showcased an object at an angle and then the object straight on. I chose about 6-8 correspondences for each image. After finding H, with help from the stackoverflow post explaining what homographies are, I generated some warped images. Here are some before and afters:

After doing so, I rectified the photos against pictures in the same plane as them. Here are the mosaics of it:

Finally, I used my blending algorithm from project 3 to blend together the photos. As you can see, the first two blended well together, but it seems like the last one didn't work too well. I am guessing that it is because the mask that I chose for the blending portion didn't fit very well to the points I chose in the project.

What I Learned

I learned how to calculate homographies for H.
