get.cont: Extract $(x; y)$ coordinates and create a Coo-object.
Description
Extracts from a set of black and white images or a list of coordinates written in a set of 2-columns ("x" and "y") .txt files.
Usage
get.cont(path)
Arguments
path
a path to indicate where are the images or the .txt files to use
Value
a Coo-object is returned.
Details
If no path is provided, the user is interactively asked to choose a folder.
get.cont uses the Conte algorithm that starts on the center of every outline in the Coo-object provided (or the imagematrix provided if Conte() is directly used). If this point does not correspond to a black pixel, i.e. not contained within the shape, the user is interactively asked to select interactively a point within the shape.
