Computational Photography Project 3 - afarley

The process of creating a mosaic starts with finding a correct perspective transform and using it to warp images into perspective. This particular project involved picking several points from pairs of images which were corresponding, calculating the transform between them, and finally warping one image to the other using that transform.

Rectification

In order that images appear correct they must be rectified into a single plane.
Here are two images and their rectified equivalents

Big Ben

Firstly there is big ben which looks a bit side heavy when rectified.

Home

A home far far away. A fairly unreal perspective. It looks like it may jut out a bit more on the right than the left. Of course this is an optical illusion.

Mosaics

Finally some nice looking mosaics. They are composed from 4 or more pictures each.

School Desk

The rectified plane is on the far left giving an extreme view of the radiator and bed.

Sideways Tree

Here the trees probably moved a bit, though it was a still day, as you can see a bit of ghosting in the lower half.
Apart from the that the tree looks fairly solid. The image unfortunately is still slightly blurry from an unsteady hand!

Waterfront

The final image was captured two summers ago in an attempt to create a mosaic with the provided software.
It turns out to quite a nice image to use for mosaics. It is too bad that the water did not come out.
There were also issues with hand rotation which obscures some close object like the telescope and part of the rug and pillow.
