This blog needs content, but grad school has all but consumed my life. I don’t have much time to organize more recent things I’m doing, but I did manage to dig some old stuff up, and I hope that they will still be interesting to readers. Here are some computer vision assignments:
Computer vision is arguably one of the most interesting class I’ve taking in my time here at Georgia Tech. The videos above show a program tracking Romney’s face/hand by means of a particle filter. Imagine a template taken beforehand being compared to a window centered at each of the dots, with the correlation between the template and window defining each dot’s weight. The red window results from taking the weighted average of each dot’s position. Neat stuff.
And here is some feature matching by means of a SIFT plus RANSAC algorithm:
Despite the picture being rotated, this program can find corresponding locations. It can even match a template to more complicated transformations. I can try to have source code put up if I can ever find them.
Until next time.
