Attributes Documentation

images

The viewport’s tkinter canvas image objects.

A numpy array of shape (rows, columns) corresponding to the viewable area of the display grid and containing the tkinter canvas image object for the face at the corresponding location.

Type:

numpy.ndarray

meshes

The viewport’s tkinter canvas mesh annotation objects.

A numpy array of shape (rows, columns) corresponding to the viewable area of the display grid and containing a dictionary of the corresponding tkinter polygon and line objects required to build a face’s mesh annotation for the face at the corresponding location.

Type:

numpy.ndarray

visible_faces

The currently visible DetectedFace objects.

A numpy array of shape (rows, columns) corresponding to the viewable area of the display grid and containing the detected faces at their currently viewable position.

Any locations that are not populated by a face will have None in it’s place.

Type:

numpy.ndarray

visible_grid

The currently visible section of the Grid

A numpy array of shape (4, rows, columns) corresponding to the viewable area of the display grid. 1st dimension contains frame indices, 2nd dimension face indices. The 3rd and 4th dimension contain the x and y position of the top left corner of the face respectively.

Any locations that are not populated by a face will have a frame and face index of -1.

Type:

numpy.ndarray
