get_connected_region

This module’s scope are algorithms to obtain regions of connected points in an array.

Example:

>>> import tuna
>>> import numpy
>>> z = numpy.zeros ( shape = ( 2, 2 ) )
>>> tuna.tools.get_connected_region ( ( 1, 1 ), z, z )
[(1, 1), (1, 0), (0, 1), (0, 0), (0, 0), (0, 1), (0, 0)]

tuna.tools.get_connected_region.get_connected_region(point, array, already)

This function’s goal is to generate a list of all points that have the same value as the input point, and that are connected to it.

Values come from array, and the array already will be updated with the points taken in consideration having the value 1, and ignoring all points that have value 1.

Parameters:

• point : tuple of 2 integers
• array : numpy.ndarray
• already : numpy.ndarray
