When I read that he used PCA to detect that they modified her bust, I really couldn't believe it. That is really impressive.
edit: I guess I should add a little background. PCA was used a good bit in computer vision (and data mining in general) when I was in school. You typically don't see it mentioned outside of those contexts.
- nostrademons 17y agoPCA is used a lot in the financial industry. You can guess how it might be useful there...
- teamonkey 17y agoI'm finding it hard to make the jump from the description on the wiki page to how you get something like the 1st Principle Component image he has there. Can anyone explain further?
