Stereoscopic image warping for enhancing composition aesthetics

The increased popularity of stereo photography due to the availability of stereoscopic lens and cameras has aroused research interest in stereo image editing. In this paper, we present an automatic, aesthetic-based warping approach to recompose both the left and right stereo image pair simultaneously using a global optimization algorithm. To maximize image aesthetics, we minimize a set of aesthetics errors formulated based on selected photographic composition rules during the warping process. In addition, our algorithm attempts to preserve the stereoscopic properties by minimizing disparity change and vertical drift in the resulting image. Experimental results shows that our approach successfully relocate salient objects according to the selected photographic rules to enhance compositional aesthetics and maintain disparity consistency to create a comfortable 3D viewing experience.
