FAST corner detector

Implementation of the FAST corner detection algorithm.

Description

The code here is an implementation of the FAST corner detection algorithm. A pixel is defined as a corner if (in a circle surrounding the pixel), N or more contiguous pixels are all significantly brighter then or all significantly darker than the centre pixel. The ordering of questions used to classify a pixel is learned using the ID3 algorithm. This detector has been shown to exibit a high degree of repeatability.

This is detailed in the following paper:

Instructions for use are included in example.m as well as matlab HELP descriptions.

It does what is supposed to do, but the code is extremely bad written

The code is not badly written - it's machine generated.
