Abstract: Certain aspects relate to systems and techniques for efficiently recording captured plenoptic image data and for rendering images from the captured plenoptic data. The plenoptic image data can be captured by a plenoptic or other light field camera. In some implementations, four dimensional radiance data can be transformed into three dimensional data by performing a Radon transform to define the image by planes instead of rays. A resulting Radon image can represent the summed values of energy over each plane. The original three-dimensional luminous density of the scene can be recovered, for example, by performing an inverse Radon transform. Images from different views and/or having different focus can be rendered from the luminous density.

Abstract translation: 某些方面涉及用于有效地记录所捕获的全光图像数据并用于从所捕获的全息数据中渲染图像的系统和技术。 全光图像数据可以由全光或其他光场摄像机捕获。 在一些实现中，可以通过执行Radon变换来将四维辐射数据转换成三维数据，以通过平面代替光线来定义图像。 得到的氡图像可以表示每个平面上的能量的总和值。 可以例如通过执行逆Radon变换来恢复场景的原始三维发光密度。 来自不同视图和/或具有不同焦点的图像可以从发光密度呈现。
