Project 6A: Image Warping and Mosaicing Part A

Daniel Shi - abl

Shoot the Pictures

I lack any sort of artistic creativity, so here are some photos taken from around my apartment.

Image Rectification

By computing a homography between 4 points of an image and a rectangle, we can morph the image into a "top down" view.

Blend the images into a mosaic

Taking the idea from the previous part, we can create a mosaic by computing a homography of two different images and then blend the warped images together.

What I learned

I learned how to compute a homography from a given set of points and use this homography to warp one image into the persepctive of another. With this, I learned to create a mosaic from the warped images.

I also found out that I'm very, very bad at taking photos. I had to use a slip day because none of my pictures would come out right :^).
