| 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 |
