CASUAL STEREOSCOPIC PHOTO AUTHORING
ABSTRACT:
In this paper, we present a method for easy stereoscopic photo authoring with a regular
(monocular) camera. Our method takes two images or video frames using a monocular camera as
input and transforms them into a stereoscopic image pair that provides a pleasant viewing
experience. The key technique of our method is a perceptual-plausible image rectification
algorithm that warps the input image pairs to meet the stereoscopic geometric constraint while
avoiding noticeable visual distortion.
Our method uses spatially-varying mesh-based image warps. Our warping method encodes a
variety of constraints to best meet the stereoscopic geometric constraint and minimize visual
distortion. Since each energy term is quadratic, our method eventually formulates the warping
problem as a quadratic energy minimization which is solved efficiently using a sparse linear
solver.
Our method also allows both local and global adjustments of the disparities, an important
property for adapting resulting stereoscopic images to different viewing conditions. Our
experiments demonstrate that our spatially-varying warping technique can better support casual
stereoscopic photo authoring than existing methods and our results and user study show that our
method can effectively use casually-taken photos to create high-quality stereoscopic photos that
deliver a pleasant 3D viewing experience.
