Partial 2D to S3D conversion and the cognitive characteristics

2D to stereoscopic 3D (S3D) conversion methods, which is one approach to creating S3D content, are divided into automatic "on-line" and manual "off-line" methods. Off-line conversion of 2D to S3D is expensive, but offers higher S3D image quality. Moreover, while off-line conversion provides more flexible control over parallax than stereo filming, in most cases, 2D images are converted according to the monocular depth cues. The authors propose a new method that adds uncrossed parallax to entire 2D images and crossed parallax only to specific areas. The authors conducted subjective and objective evaluations to examine the cognitive characteristics of partial 2D to S3D conversion. This paper describes the details of the proposed method and the results of the evaluations.
