Making stereo photo cropping easy
Fan Zhang, Yuzhen Niu, Feng Liu · 2013
The increasing popularity of stereoscopic 3D brings the demand for tools for editing and authoring stereoscopic images and videos. This paper shows that even a simple task like cropping is difficult for amateur users with little stereoscopic photography knowledge. Unlike regular monocular (2D) images, cropping a stereoscopic image needs to be carefully executed to avoid stereoscopic violations, which otherwise cause an unpleasant stereoscopic viewing experience. In this paper, we present a system that assists in stereoscopic photo cropping by automatically measuring the stereoscopic photography violations and alerting users with the potential violations. Our study shows that compared to a popular stereoscopic photo editing system, our system makes stereoscopic photo cropping easier even for amateur users with little stereoscopic photography knowledge and provides a good user experience.
