Illustration of assumptions made in related problem domains in image assembly and document reconstruction.
(a) A pair of overlapping images of a natural scene (green box highlights region of overlap). (b) Photograph of a natural scene with no missing pieces (whole image highlighted in green, stitched subimages boxed in dashed lines). (c) Interlocking archetypal jigsaw puzzle pieces (green arrows highlight interlocking edges). (d) Two corresponding prostate histology quadrants, which do not overlap (red box highlights region of non-overlap). (e) A stitched PWMHS which lacks completeness (whole image outlined in green, missing pieces outlined in red). (f) Non-interlocking prostate histology quadrants (red X’s highlight lack of interlocking edges).
