EM constructor

model = cv.EM()
model = cv.EM(filename)

Creates empty EM model. The model should be trained then using train method. Alternatively, you can use one of the other train* methods or load it from file using load method.

In the second form (with given file name as an input), the new object is created, which then loads parameters (options, trained weights, means and covariations) which were saved to this file by some earlier created object.

Input

• filename Name of XML or YML file, containing previously saved model
