extract.otf.image.3d: Title Optimal Transport Allocation and Transport between 3D...

In samuelgerber/OTFeatures: What the Package Does (One Line, Title Case)

Description

Compute optimal transport between X and Y and create allocation and transport images

Usage

extract.otf.image.3d(
  from.image,
  to.image,
  mass.cost = 0,
  transport.type = 3,
  p.degree = 2
)

Arguments

from.image	3d array
to.image	3d array
mass.cost	cost of allocating or removing mass
transport.type	optimal transport mode default=3: \n 0 - Balanced (equalizes source and target mass) 1 - Add mass (Only allow addition of mass in soutrce or target) 2 - Subtract mass (Only allow subtraction of mass in source or target) 3 - Match source mass (Add or subtract in source to match target) 4 - Free (Add or subtract mass anywhere) 5 - Free source only (Add or subtract mass in source only)
p.degere	optimal transport cost degree (i.e. cost^p.degreee)

Value

list with allocation and trasnport cost images in from and to

Examples

data(brains)
otf = extract.otf.image.3d(brain1, brain2)
par(mfrow=c(2,2))
image(brain1[,,2])
title("From")
image(brain2[,,2])
title("To")
image(brain1[,,2] - brain2[,,2])
title("Difference Per Voxel")
image(otf$difference.from[,,2])
title("Mass Allocation in From")
