WARNING :
All images must have an isotropic image resolution (cubic voxels).
Image intensities should be integers.


---------- File PO.hpp ----------

PO_3D : 
Compute the Path Opening operator in one orientation. The 7 orientations are defined in the function createNeighbourhood.

	I : Input image
	L : Path length
	index_image : sorted index of the image. Result of the sort_image_value function of sorting.hpp 
	orientations : defined the orientation used. Choices are [0,0,1] ; [1,0,0] ; [0,1,0] ; [1,1,1] ; [-1,1,1] ; [1,1,-1] ; [-1,1,-1]
	Output : Result of the Path Opening
	

---------- File RPO.hpp ----------

RPO :
Compute the 7 orientations of the Robust Path Opening and return them.

	I : input image
	L : Path length
	RPO1 : resulting Robust Path Opening in the first orientation.
	RPO2 : resulting Robust Path Opening in the second orientation
	RPO3 : resulting Robust Path Opening in the third orientation
	RPO4 : resulting Robust Path Opening in the fourth orientation
	RPO5 : resulting Robust Path Opening in the fifth orientation
	RPO6 : resulting Robust Path Opening in the sixth orientation
	RPO7 : resulting Robust Path Opening in the seventh orientation
	nb_core : number of cores used to compute the Path Opening (choose between 1 and 7)
	

---------- File RORPO.hpp ----------
Compute the Ranking Orientations Responses of Path Operators (RORPO)

	I : input image
	L : Path length
	nb_core : number of cores used to compute the Path Opening (choose between 1 and 7)
	

---------- File RORPO_multiscale.hpp ----------
Compute the multiscale RORPO

	I : input image
	S_list : vector containing the different path length (scales)
	nb_core : number of cores used to compute the Path Opening (choose between 1 and 7)
	debug_flag : 1 (activated) or 0 (desactivated)
	Mask : optional mask image
