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:http://www.edwardrosten.com/work/fast.htmlWhy 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!Why FAST-9?
It seems that FAST-9 corners (using 9-point segments) have higher repeatability than the other ones (i.e.
FAST12, FAST11, etc.).
