class menpo.fit.regression.base.Regressor(regressor, features)[source]¶

An abstract base class for fitting Regressors.

Parameters:

regressor: function/closure :

The regressor to be used from menpo.fit.regression.regressionfunctions.py.

features: :

The features used to regress.

fit(image, initial_parameters, gt_shape=None, **kwargs)¶

Fits the fitter object to an image.

Parameters:

image: :class:`menpo.image.masked.MaskedImage` :

The image to be fitted.

initial_parameters: list :

The initial parameters of the model.

gt_shape: :class:`menpo.shape.PointCloud`, optional :

The original ground truth shape associated to the image.

Default: None

Returns:

fitting_result: `menpo.fit.fittingresult` :

The fitting result.

update(delta_p, initial_shape)[source]¶: Abstract method to update the parameters.
