sksurgeryeval.algorithms.algorithms module

Algorithms for the surgery evaluation application

sksurgeryeval.algorithms.algorithms.add_map(config)

Loads vtk models from a directory and returns a list of vtk actors, with mesh visualisation

Param:configuration, may contain a “map” key Param:model_to_world: 4x4 matrix, of dtype float32 Returns:actors, None if no “map” key

sksurgeryeval.algorithms.algorithms.configure_tracker(config)

Configures the tracking system. :param: A dictionary containing configuration data :return: The tracker object :raises: KeyError if no tracker entry in config

sksurgeryeval.algorithms.algorithms.np2vtk(mat)

Converts a Numpy array to a vtk matrix :param: the number array, should be 4x4 :return: a vtk 4x4 matrix :raises: ValueError when matrix is not 4x4

sksurgeryeval.algorithms.algorithms.point_in_locator(point, point_locators, radius=1.0)

Tests whether a point is within a set distance of any of a list of point locators.

Parameters:

• point – the point to test, in 3D (x,y,z)
• point_locators – a list of vtkPointLocators
• radius – optional search radius in mm (default=1.0)

Return locator:

the index of the nearest point locator,

-1 if no locators within radius) :return distance: distance to nearest point_locator

Raises:delegates to vtk

sksurgeryeval.algorithms.algorithms.populate_models(config)

Loads vtk models from a directory and returns a list of vtk actors and associated vtkPointLocators

Param:configuration, should contain a target value Param:model_to_world: 4x4 matrix, of dtype float32 Returns:locators Returns:actors Raises:KeyError if target not in config

sksurgeryeval.algorithms.algorithms.random_targets(count)

Create a list of targets
