Feature matching options.
There are no default values, all fields must be initialized.

int sfm::Matching::Options::descriptor_length |
The length of the descriptor.
Typically 128 for SIFT, 64 for SURF.
Definition at line 34 of file matching.h.
float sfm::Matching::Options::distance_threshold |
Does not accept matches with distances larger than this value.
This needs to be tuned to the descriptor and data type used. Set to FLOAT_MAX to disable the test.
Definition at line 49 of file matching.h.
float sfm::Matching::Options::lowe_ratio_threshold |
Requires that the ratio between the best and second best matching distance is below some threshold.
If this ratio is near 1, the match is ambiguous. Good values are 0.8 for SIFT and 0.7 for SURF. Set to 1.0 to disable the test.
