摘要

焦点叠加作为光场的另一种表现形式引起了人们的关注。然而，从其FS重建LF的问题被认为是不适定的。虽然讨论了许多正则化方法，但没有一种方法能完美地解决这个问题。本文证明了在无遮挡的兰伯场景中，如果获取FS的相机光圈为柯西函数，则可以通过滤波器组对FS进行理论上的重构。数值模拟结果表明，该滤波器组可以很好地重建低频信号。

Filter Bank for Perfect Reconstruction of Light Field from Its Focal Stack

Focal stacks (FS) have attracted attention as an alternative representation of light field (LF). However, the problem of reconstructing LF from its FS is considered ill-posed. Although many regularization methods have been discussed, no method has been proposed to solve this problem perfectly. This paper showed that the LF can be perfectly reconstructed from the FS through a filter bank in theory for Lambertian scenes without occlusion if the camera aperture for acquiring the FS is a Cauchy function. The numerical simulation demonstrated that the filter bank allows perfect reconstruction of the LF.
