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 - - |
