Abstract: In this paper, we present an interactivestatic image composition approach, namelycolor retargeting, to flexibly represent time-varying colorediting effect based on time-lapse video sequences.Instead of performing precise image matting orblending techniques, our approach treats the colorcomposition as a pixel-level resampling problem. Inorder to both satisfy the user’s editing requirements andavoid visual artifacts, we construct a globally optimizedinterpolation field. This field defines from which inputvideo frames the output pixels should be resampled.Our proposed resampling solution ensures that (i) theglobal color transition in the output image is as smoothas possible, (ii) the desired colors/objects specified bythe user from different video frames are well preserved,and (iii) additional local color transition directions inthe image space assigned by the user are also satisfied.Various examples have been shown to demonstrate thatour efficient solution enables the user to easily createtime-varying color image composition results.
