Color retargeting: Interactive time-varying color image composition from time-lapse sequences

Journal Contribution - Journal Article

In this paper, we present an interactive
static image composition approach, namely
color retargeting, to flexibly represent time-varying color
editing effect based on time-lapse video sequences.
Instead of performing precise image matting or
blending techniques, our approach treats the color
composition as a pixel-level resampling problem. In
order to both satisfy the user’s editing requirements and
avoid visual artifacts, we construct a globally optimized
interpolation field. This field defines from which input
video frames the output pixels should be resampled.
Our proposed resampling solution ensures that (i) the
global color transition in the output image is as smooth
as possible, (ii) the desired colors/objects specified by
the user from different video frames are well preserved,
and (iii) additional local color transition directions in
the image space assigned by the user are also satisfied.
Various examples have been shown to demonstrate that
our efficient solution enables the user to easily create
time-varying color image composition results.
