Mosaics/Panorama Project (PART I)

First I tried to get my projective to work on a single image, to produce a recitifed image.
Here is an example:

Another example

Now with linear blending, I managed to stitch the following three pictures together:

This resulted in the following mosaic:

Here is the same image but with expanded alpha-blending where I used a gaussian window to determine the alpha which resulted in a slightly nicer result.

Here is another example
Here are the source images:

Here is the resulting mosaic (for some reason there's a little artifact in the middle that I couldn't get rid of):

Here is some fun things I did with panorama stitching:
Who needs to buy new guitars when you can just multiply them via panarama stiching? (Note: i didn't have a tripod so the results are iffy, also I used linear blending which furthered the iffiness)

Here's a mosaic stiching of a stitched mosaic (found in Gates). The result is not distorted which I thought was surprising:
