Parameters

model
Type: System..::..IntPtr
The EM model
samples
Type: System..::..IntPtr
The training data. A 32-bit floating-point, single-channel matrix, one vector per row
labels
Type: System..::..IntPtr
Can be IntPtr.Zero if not needed. Optionally computed output "class label" for each sample
probs
Type: System..::..IntPtr
Initial probabilities p_{i,k} of sample i to belong to mixture component k. It is a one-channel floating-point matrix of nsamples x nclusters size.
logLikelihoods
Type: System..::..IntPtr
The optional output matrix that contains a likelihood logarithm value for each sample. It has nsamples x 1 size and CV_64FC1 type.

Return Value

The methods return true if the Gaussian mixture model was trained successfully, otherwise it returns false.
