researc...We introduce high
dynamic range image
hallucination for adding high
dynamic range details to the
over-exposed and under-exposed
regions of a low dynamic range
image. Our method is based on
a simple assumption: there
exist high quality patches in
the image with similar
textures as the regions that
are over or under exposed.
Hence, we can add high dynamic
range details to a region by
simply transferring texture
details from another patch
that may be under different
illumination levels. In our
approach, a user only needs to
annotate the image with a few
strokes to indicate textures
that can be applied to the
corresponding under-exposed or
over-exposed regions, and
these regions are
automatically hallucinated by
our algorithm. Experiments
demonstrate that our simple,
yet effective approach is able
to significantly increase the
amount of texture details in a
wide range of common
scenarios, with a modest
amount of user interaction.
