'Filling-In Illusion'.
This is a tentative explanation for how the colours come to fuse
in the other examples. No image fusion is required.
The illusion works best when there is no
boundary between the differently coloured areas.
Counter Examples to
the idea that the Filling-In Illusion is responsible for the
Bicovi effect are presented. The examples show that the Bicovi colour
fusing works best with a boundary, contrary to the Filling-In
Illusion.
If the central boundary is simply removed,
the darker colours will be obvious and fusion will not occur to
give a match for the surrounding reference colour. (See
also the "Whiter"
section.)
However, colour matching can be achieved by
equalizing
the Values of the central and surround colours. This is
reflected in the "Value Corrected" links.
