What is this?
This simple demo app takes the live camera feed, detects the FAST9 corners based on the method by E. Rosten, and displays the results in a smaller window in near real-time. See here for more details:
Why FAST detector?
FAST (Features from Accelerated Segment Test) can be computed very quickly. Great for real-time visual tracking. Of course, descriptors are not implemented in this project. If someone wants to do that, please feel free, and share your code with us!
It seems that FAST-9 corners (using 9-point segments) have higher repeatability than the other ones (i.e.
FAST12, FAST11, etc.).
