Computational optical imaging methods allow the extension of the functionality of traditional cameras. The shape of the aperture in an optical system determines the shape in which the out-of-focus points are blurred in a captured image. In this work we present a method in the Fourier domain that allows us, from an acquired multi-focus image stack, to synthesize images of a three-dimensional scene as if they had been acquired with apertures with arbitrary shapes. Partially extended depth-of-field as well as all-in-focus image reconstruction can be obtained as particular cases.
计算光学成像方法能够扩展传统相机的功能。光学系统中孔径的形状决定了拍摄图像中失焦点模糊的形状。在这项工作中，我们提出了一种傅里叶域方法，该方法使我们能够从采集到的多焦点图像堆栈中合成三维场景的图像，就好像这些图像是用具有任意形状孔径的相机采集的一样。部分扩展景深以及全聚焦图像重建可作为特殊情况得到。
