+Description:
+Library to compute FAST features with non-maximum suppression.
+
+The files are valid C and C++ code, and have no special requirements for
+compiling, and they do not depend on any libraries. Just compile them along with
+the rest of your project.
+
+To use the functions, #include "fast.h"
+
+The corner detectors have the following prototype (where X is 9, 10, 11 or 12):
+
+xy* fastX_detect_nonmax(const unsigned char * data, int xsize, int ysize, int stride, int threshold, int* numcorners)
+
+Where xy is the following simple struct typedef:
+
+typedef struct
+{
+ int x, y;
+} xy;
+
+The image is passed in as a block of data and dimensions, and the list of
+corners is returned as an array of xy structs, and an integer (numcorners)
+with the number of corners returned. The data can be deallocated with free().
+Nonmaximal suppression is performed on the corners. Note that the stride
+is the number of bytes between rows. If your image has no padding, then this
+is the same as xsize.
+
+The detection, scoring and nonmaximal suppression are available as individual
+functions. To see how to use the individual functions, see fast.c
+
+Local Modifications:
+Add lines to turn off clang formatting for these files
+Remove Fast 10, 11 and 12
+Convert tabs to spaces
+Prefix global functions with "aom_"
