목적: 3D TV의 근거리 시청에 따른 사위와 조절성폭주비의 변화와 회복 시점을 평가하고자 하였다. 방법: TV 시청이 가능한 20~40대의 50명(남 30명, 여 20명)을 대상으로 하웰(Howell) 사위 카드를 사용하여 원거리(3 m)와 근거리(40 cm)에서 사위도를 측정하였다. 시청 거리는 1 m이며 전, 시간 30분 동안 10분 간격으로, 이후 5분 간격으로 결과: 영상 시청의 원거리 사위도 변화는 3D영상 전 <TEX>$-0.80{\pm}1.12{\Delta}$</TEX>과 비교하여 10분, 후 각각 <TEX>$-0.98{\pm}1.37{\Delta}$</TEX>(p=0.063), <TEX>$-1.00{\pm}1.28{\Delta}$</TEX>(p=0.024)로 외사위 경향으로 증가하였으며, 종료 후에는 외사위도가 감소하기 시작하여 20분 이후에는 <TEX>$-0.78{\pm}1.11{\Delta}$</TEX>로 수준으로 회복되었다(p=0.322). 역시...

This paper evaluates the performance of patterns used to solve a very challenging problem in close range photogrammetry and computer vision when surface object or scene is textureless. Three dimensional modeling from arbitrary viewpoints an active field research due its wide applications. However, structure-from-motion, common approach for objects that are not well textured fails insufficient discriminative features images hence results incomplete inaccurate three model surface. Mainly, two...

Most UHDTV content is presently created using single large CMOS sensor cameras as opposed to 2/3-inch small cameras, which the standard for HD content. The consequence a technical incompatibility that does not only affect lenses and accessories of these but also creation process in 2D 3D. While generally acclaimed its superior image quality, sensors have introduced new constraints filming process. camera sizes lens dimensions obstacles their use 3D production. recent availability broadcast...

Subtitles in Digital Cinema are well established for monoscopic formats.They often used, when dubbing is not available such as film festivals and international arthouse distribution.A wide range of authoring tools subtitles can easily be added Packages.This simple language version creation method facilitates distribution movies.Mastering stereoscopic movies however, requires specialized visualization authoring.It therefore common to see with lower quality or no all the versions burned into...

This paper presents the Fantatrope, an improvement of pre-cinematographic devices such as zoetrope, which creates a comfortable 3D display with addition ultra-realistic full-color holograms.
