Abstract
- Stereoscopic image retargeting aims to manipulate the stereoscopic images to fit various devices with different resolutions and prescribed aspect ratios. With the development of various types of three-dimensional (3D) displays, stereoscopic image retargeting becomes increasingly popular in the field of computer graphics. In this paper, we propose an unsupervised stereoscopic image retargeting network (USIR-Net) to address the problem of stereoscopic image retargeting without label information. By exploring the inter-view correlation and disparity relationship of stereoscopic images, two unsupervised losses are developed to guide the learning of stereoscopic image retargeting model. First, in view of the inter-view correlation, a view synthesis loss is proposed to guarantee the generation of high-quality stereoscopic images with accurate inter-view relationship. Second, by exploiting the consistency of stereoscopic images before and after the retargeting, a stereo cycle consistency loss, which consists of a content consistency term and a disparity consistency term, is developed to preserve the structure information and prevent binocular disparity inconsistency. Quantitative and qualitative experimental results demonstrate that the proposed method achieves superior performance compared with state-of-the-art methods. [ABSTRACT FROM AUTHOR]
