vquilt − combine a set of images into a single image

vquilt [if=<inputfile>] [of=<outputfile>] [rf=<referencefile>] [-m] [-p]

Vquilt Combines a set of images into a single image. This can be used to reconstruct an image that was decomposed using Vpatch in which case only the central pixels of each patch are used. For example, if the patches overlap by 50%, only the middle 25% of each patch is used. The outer edge of the original image with a width equal to one half of the overlap is not preserved. Therefore, the resulting image is smaller than the orignal image. If the set of images do not result from vpatch, they will be combined with images later in the set overwriting images earlier in the set if overlap occurs. A minimaly large image is used for the reconstruction. Alternatively, a reference file can be supplied on which the reconstructed image will be built.

rf=<filename>

Specify the reference image which determines the size of the output image. The reference image does not need to be the same type as the image set. If the reference image is larger than the recontructed image then parts of the image not covered by the image patches are set to zero value. The reference image may be smaller than the recontructed image in which case some patch information is omited.

-m

The images will be merged on top of the reference image. The reference image must be the same type as the image patches.

-p

Specify that the images were created using vpatch. The recontructed image will contain the central pixels from each patch.
