Image Warping and Mosaicing

Picture Time!

We first take photos with (ideally) the same aperture and exposure. To get multiple images we rotate the camera on a constant axis to get multiple images.

Test Run...

To test our homographies, we run the homography on a single image and try to change the perspective of something specific on the image. For example, in this example we try to align one of the windows to a square.

Average blend

After applying the homographies, we get diffrent perspectives of the same object in space. We then take the weighted average of both in an attempt to blend the images. As you will see, the results are rather disappointing.

Laplacian blend

Let's try a Laplacian blend instead. Which is better?

Cool Parts!

This project made me notice the basis for interesting technologies such as the feature in Google Earth where you can walk on the streets, also certain virtual reality applications. It also showed me that some ideas we learned in the past are still relevant, like Laplacian blending!
