ROC Curve


Below are ROC curves for graf and Yosemite. The ratio match tend to have better ROC curves than the SSD match.

Test sequence


The brick building standing in the middle of a very green lawn is an imposing sight.

Bands was 0 based, but we thought it would be 1 based, and the picture came out blue. Also, the solution didn't seem to be using random numbers correctly.

Sequence with Kaiden panorama head


1. Physics Building

This is the pendulum in the Physics Building. I really like the striking red brick of the mysterious hallway that leads to bowels of the building. The obtuse angle between the two hallways also adds an interesting element to the panorama because it looks less distorted than hallways at a right angle.

Reflection of pillar in window made it hard, since one portion of the pillar was matching the reflection, instead of the pillar.

2. Overpass

I was hoping for a more dramatic stream of car lights to and away from the city, but the overpass was too wide to get this image. I got a call in the middle of taking these shots, which accounts for the more than normal decrease in lighting over the panorama.

First and last pictures have different lighting, so it was hard to match them. We had to pull the pictures together closer to match them.

3. Botany GreenHouse

I really like the dark patch of the greenhouse with the sun shining through the window. It really contrasts the liveliness of the cacti to the sides of the panorama.

Camera was at different tilts, and bottom and top of pictures do not align. We had to manually adjust alignments for most of the pictures. Also, there were so many features and it took a lot longer to compute and match them.

4. Henry Art Gallery

We thought the Henry Art Gallery would be another good panoramic picture because the colorful tower next to the museum provides a nice relief to the otherwise dark entry to the University of Washington. Lucky for us, the gallery was open when we were taking pictures, and I think the people add a bit of life to the image.

Due to the mostly dark pictures, a few of the images that look away from the gallery were manually stitched together.

5. Mural

The color of the murals is a nice contrast to the dull alley colors. I also like the reflection of the mural in the window. And, the parked FedEx truck is a cute reminder of the everyday activity that happens in the back of the art store.

Same shape garage door matched wrong locations. Dark pictures had too few features to match properly. On the other hands, the graffiti had too many features and it seemed like many of them accidentally matched worng ones.

Sequence taken by hand


Oh no! We had too much fun in this lab!

It is obvious that this series is the "hand held" shots. I am unsure what the focal length of my camera phone is, so I adjusted it until the first two warped images differed by what seemed a simple translation. Most pictures needed manual alignment adjust to match properly.

We had the same person to appear in many pictures for fun.
