Audience discomfort, such as eye strain and dizziness, is one of the urgent issues that virtual reality and 3D movie technologies should tackle. Except for inappropriate horizontal and vertical disparity, one major problem is that people's binocular vergence and focal length in the cinema remain inconsistent from normal visual habits. Psychologists discovered the horopter and Panum's fusional area to describe zero-disparity points projected on the retinas based on accommodation-convergence consistency. In this paper, inspired by these concepts, we propose a stereoscopic effect correction system for perceptual enhancement according to fixated region and scene information. As a preprocessing step, tracking and stereo matching algorithms are implemented to prepare cues for further transformation in 3D space. Then in order to accomplish certain visual effects, we describe a geometric framework for disparity refinement and image warping based on parameter adjustment of the virtual stereoscopic rig. For evaluation, subjective experiments have been conducted to prove the effectiveness of our method. Therefore, our work provides a possibility to improve the audience experience from a formerly underexplored perspective.

Structured light 3D scanning has many applications such as 3D modeling, animation, motion analysis, deformation measurement and so on. Traditional structured light methods make use of a sequence of patterns to obtain the dense 3D data of objects. However, few methods have been proposed to achieve pixel wise reconstruction using one pattern only. In this paper, we proposes a one-shot scanning system based on a novel stripe pattern. This pattern uses color stripes with quadratic intensity distribution in each stripe. The color distribution is based on a De Bruijn sequence with six colors and order three. Graph cut is utilized to decode the color information and the resulting code is calculated using local intensity. Compared with traditional methods, the proposed method uses one pattern only and achieves pixel wise reconstruction. Experimental results show that our one-shot scanning system can robustly capture 3D data with high accuracy.
