Reconstruct image from a list of patches.

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.
