My fall adventure

I doubt anyone noticed, but I was absent a lot this fall. Whole days would go by without a visit to MR. I was gone because I was taking several classes.

I just finished a project for one class, and I'm proud enough that I wanted to share it with you. It's pretty technical, but I bet there are a number of people here who will understand it.

I wrote a program that matched a picture downloaded from Google images with one found in a target photo. For example, I did a Google search on "spam" and then used one of the results. The goal is to find enough similarity between the 2 images that you can reliably say that they show the same thing.

I'm sure you're thinking that this is easy. Did you know that (I think) a quarter of the human brain is devoted to vision? A significant portion of the vision processing in the human brain occurs without conscious thought. Also, it took your brain years to learn how to see objects. This is not an innate ability (I've worked with teenagers, so I know this for a fact). Duplicating this ability is still an interesting problem in computer vision.

some technical detail
The project was written based on the goals set in The Semantic Robot Vision Challenge. The program was written in matlab, and I relied heavily on VLFeat library. I used Harris corners to select the points to try to match, and SIFT to describe the points and match them.

With some refinement, my program is good enough that I'm planning to use it to compete next year. Some success images follow. Enjoy.

I did notice as I always try to read your posts. They are not always understandable (like this one) but I figure I'll learn something.

Congratulations on the finished project and Good Luck when you enter the competition.

This is cool, Nate!! I've often wished there was a scan option to match a picture to google image results...

Sounds like a tough project. I think I read somewhere that Google is working on something like this? It's hard for me to imagine that a computer program can do something like this. Congrats on completing your project!
