reconstructImageFromPatches: Reconstruct image from a list of patches.

In ANTsX/ANTsRNet: Neural Networks for Medical Image Processing

Reconstruct image from a list of patches.

Description

Reconstruct image from a list of patches.

Usage

reconstructImageFromPatches(
  patches,
  domainImage,
  strideLength = 1,
  domainImageIsMask = FALSE
)

Arguments

patches	List or array of patches defining an image. Patches are assumed to have the same format as returned by extractImagePatches.
domainImage	Image or mask to define the geometric information of the reconstructed image. If this is a mask image, the reconstruction will only use patches in the mask.
strideLength	Defines the sequential patch overlap for maxNumberOfPatches = all. Can be a image-dimensional vector or a scalar.
domainImageIsMask	boolean specifying whether the domain image is a mask used to limit the region of reconstruction from the patches.

Value

an ANTs image.

Examples

library( ANTsR )

image <- antsImageRead( getANTsRData( "r16" ) )
patchSet <- extractImagePatches( image, c( 64, 64 ), "all", c( 8, 8 ) )
imageReconstructed <-
  reconstructImageFromPatches( patchSet, image, c( 8, 8 ) )
testthat::expect_equal(as.array(image), as.array(imageReconstructed))
rm(image); gc()
rm(patchSet); gc()
rm(imageReconstructed); gc()
