ImageQuilting.IQType
IQ(var₁=>param₁, var₂=>param₂, ...)

Image quilting simulation solver as described in Hoffimann et al. 2017.

Parameters

Required

  • trainimg - Training image from which to extract tiles
  • tilesize - Tuple with tile size for each dimension

Optional

  • path - Simulation path (:raster (default), :dilation, or :random)
  • mapping - Data mapping method (default to NearestMapping())
  • inactive - Vector of inactive voxels (i.e. CartesianIndex) in the grid
  • soft - A vector of (data,dataTI) pairs
  • tol - Initial relaxation tolerance in (0,1] (default to 0.1)

Global parameters

Optional

  • threads - Number of threads in FFT (default to number of physical CPU cores)
  • gpu - Whether to use the GPU or the CPU (default to false)
  • showprogress - Whether to show or not the estimated time duration (default to false)
