Member Function Documentation
| void vpdt_mog_updater< mog_type >::insert | ( | mog_type & | mixture, |
| const F & | sample, | ||
| T | init_weight | ||
| ) | const [inline, protected] |
insert a sample in the mixture.
- Parameters:
-
sample A Gaussian is inserted with a mean of sample and a covariance from init_gaussian_ init_weight The normalized weight the resulting sample should have after insertion
Definition at line 44 of file vpdt_update_mog.h.
| unsigned int vpdt_mog_updater< mog_type >::match | ( | const mog_type & | mix, |
| const F & | sample, | ||
| const T & | gt2, | ||
| T & | sqr_dist | ||
| ) | const [inline, protected] |
Return the index of the first Gaussian within the threshold distance.
The threshold gt2 is on the square distance. The computed square distance is returned by reference in sqr_dist If there are no matches return the number of components (last index + 1)
