- 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_"
