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

• overlap - Overlap size (default to (1/6, 1/6, ..., 1/6))
• 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 pair (data,dataTI) of geospatial data objects (default to nothing)
• 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)
• showprogress - Whether to show or not the estimated time duration (default to false)
• rng - Random number generator (default to Random.GLOBAL_RNG)
