The MCvEMParams type exposes the following members.
Fields
| Name | Description | |
|---|---|---|
| cov_mat_type |
The type of the mixture covariation matrices
| |
| covs |
Initial mixture covariation matrices S_k; are used (if not NULL) only when start_step=CvEM::START_E_STEP.
| |
| means |
Initial mixture means a_k; are used (and must be not NULL) only when start_step=CvEM::START_E_STEP.
| |
| nclusters |
The number of mixtures
| |
| probs |
Initial probabilities p_i,k; are used (and must be not NULL) only when start_step=CvEM::START_M_STEP
| |
| start_step |
The initial step the algorithm starts from
| |
| term_crit |
Termination criteria of the procedure. EM algorithm stops either after a certain number of iterations (term_crit.num_iter), or when the parameters change too little (no more than term_crit.epsilon) from iteration to iteration
| |
| weights |
Initial mixture weights pi_k; are used (if not NULL) only when start_step=CvEM::START_E_STEP
