압축 라이트 필드 획득을 위해 코딩된 조리개 이미징이 활용되었습니다. 다양한 조리개 패턴을 사용하여 여러 이미지를 캡처하고 해당 이미지에서 전체 라이트 필드가 계산적으로 재구성됩니다. 이 방법은 동적 조명 필드(움직이는 장면)로 확장되었습니다. 그러나 이 방법에서는 패턴이 회색 값이고 임의의 모양이라고 가정했습니다. 이러한 패턴을 구현하려면 LCoS(Liquid Crystal On Silicon) 디스플레이와 같은 특수 장치가 필요했는데, 이로 인해 이미징 시스템이 비용이 많이 들고 노이즈가 발생하기 쉽습니다. 이 문제를 해결하기 위해 우리는 시간에 따라 회전하는 바이너리 조리개 패턴의 사용을 제안하며, 이는 구멍이 있는 회전판으로 구현할 수 있습니다. 우리는 이러한 패턴을 사용하면 설계 공간이 제한되지만 우리 방법은 원래 방법에 필적하는 높은 재구성 품질을 여전히 달성할 수 있음을 보여줍니다.

Abstract: Coded-aperture imaging has been utilized for compressive light field acquisition; several images are captured using different aperture patterns, and from those images, an entire light field is computationally reconstructed. This method has been extended to dynamic light fields (moving scenes). However, this method assumed that the patterns were gray-valued and of arbitrary shapes. Implementation of such patterns required a special device such as a liquid crystal on silicon (LCoS) display, which made the imaging system costly and prone to noise. To address this problem, we propose the use of a binary aperture pattern rotating along time, which can be implemented with a rotating plate with a hole. We demonstrate that although using such a pattern limits the design space, our method can still achieve a high reconstruction quality comparable to the original method.

AB - Coded-aperture imaging has been utilized for compressive light field acquisition; several images are captured using different aperture patterns, and from those images, an entire light field is computationally reconstructed. This method has been extended to dynamic light fields (moving scenes). However, this method assumed that the patterns were gray-valued and of arbitrary shapes. Implementation of such patterns required a special device such as a liquid crystal on silicon (LCoS) display, which made the imaging system costly and prone to noise. To address this problem, we propose the use of a binary aperture pattern rotating along time, which can be implemented with a rotating plate with a hole. We demonstrate that although using such a pattern limits the design space, our method can still achieve a high reconstruction quality comparable to the original method.
