FAST Corner Detection for the iPhone Version 2.0
FAST Corner Detection is an algorithm developed by Edward Rosten (Ed's resource-rich FAST webpage found here ). It is a very efficient algorithm for detection of corners in pictures. With the curteous consent and excitement of Ed, Success Labs ported the existing FAST library to the iPhone, to see it run in real-life environments and in real-time. Version 2.0 of this port, is a major advancement from the previous one: * Much better frame rate (FPS) * Rendering using OpenGL * Corners never lose sync with picture * More configuration and eye candy * use of Non Max Suppression available * and more! Some configurations achieve a brilliant 30 FPS, with great looking results. We present the improvements and optimizations done in our forums here . The app is available on the AppStore: (Please update to 2.0 if you haven't yet) Licensing As of the 2nd version, we introduce 2 usage license: Private Use (Free) - For private use, academic research, coding tips, examples and such, the code can still be downloaded in its whole completely free.
