I made another attempt at acquiring source images for my Thesis on Friday.
The images below were taken on top of the UNM bookstore looking out at the new Architecture building, the Frontier restaurant, and Central Avenue.

The digital panoramic photo mosaic process involves taking multiple overlapping source photographs of a scene from slightly different vantage points and then digitally "stitching" these images together to form a single composite image that appears as if is was taken from a higher resolution and a possibly wider angle camera.
An example of photo mosaic of UNM's Zimmerman Library follows. A 2×11 matrix of source photographs is shown, followed by the processed mosaic:

| Before: 2,336 × 3,504 pixel (~ 8.1 MegaPixel) source images arranged in a 2x11 matrix |
|
| After: photo mosaic: 16,961 × 5,792 pixels (~ 98 MegaPixels) |
This 16,961 × 5,792 pixel image is big!
One way to think about its size would be to print it out at a relatively standard 200 pixels per inch. If you did so, the print would about 7 × 2.4 feet.
Another way to think its size is to look at a small 100%-scale cropped portion of the image like the one shown below:
If you look carefully, you can see this student crossing the plaza in the right hand portion of the full mosaic.
For full-resolution high-quality output, creating one of these composite panoramas is not a trivial computational task. An example like the one shown above can take hours on a modern workstation, while processing extremely large examples like Max Lyon's GigaPixel image can take many days.
I propose an MS Thesis that will demonstrate how the performance of digital panoramic photo mosaic compositing can be improved through parallel computing. The goal will be to take a multi-day real-world serial example and after writing parallel modifications to existing serial codes, accomplish the same task much quicker in parallel (given access to sufficient computational resources).
My brother Craig Bohnsack was married on September 1st 2007 to Kayla Cichon. Naturally, I took a lot of photos. More than 600 are here.
Here's what they looked like:

This post is to make commenting about broken bone recovery easier, as the old posts, especially Broken Ankle Progress, Broken Ankle Progress (part II), and Broken Ankle Progress (part III) have so many comments, that navigation has become difficult.
So... new comments can be attached to this post, while you can continue to view old comments on those other posts.
