Survey on Stereoscopic 3D Image Retargeting

Stereoscopic 3D display technology develops rapidly. In order to ensure the perception quality in various viewing conditions, the stereoscopic image retargeting technique receives much concern in recent years. Due to the different characteristics, stereoscopic image cannot be processed directly by the retargeting methods for traditional 2D image. In this paper, after analyzing the characteristics of stereo vision and its psychological impact, we describe the issue of stereoscopic image retargeting. Then we review the proposed techniques in this research area and classify them according to their basic approaches. At last we summarize the problems in the existing stereoscopic image retargeting techniques and propose the future research direction.
