run
(image, initial_shape, gt_shape=None, max_iters=20, return_costs=False)¶ Execute the optimization algorithm.
Parameters: - image (menpo.image.Image) – The input test image.
- initial_shape (menpo.shape.PointCloud) – The initial shape from which the optimization will start.
- gt_shape (menpo.shape.PointCloud or
None
, optional) – The ground truth shape of the image. It is only needed in order to get passed in the optimization result object, which has the ability to compute the fitting error. - max_iters (int, optional) – The maximum number of iterations. Note that the algorithm may converge, and thus stop, earlier.
- return_costs (bool, optional) – If
True
, then the cost function values will be computed during the fitting procedure. Then these cost values will be assigned to the returned fitting_result. Note that the costs computation increases the computational cost of the fitting. The additional computation cost depends on the fitting method. Only use this option for research purposes.
Returns: fitting_result (
APSAlgorithmResult
) – The parametric iterative fitting result.
