摘要在这篇文章中，我们将探讨使用几个空间域的焦点度量经常应用在非相干（经典）成像系统，并评估其适用性的自动数值聚焦海洋全息图，如收集与eHoloCam，水下数字全息照相机在阿伯丁大学开发的。该方法将应用于一组粒子全息图，这些粒子全息图被选择来表示三个类别中的一系列特征：不透明度、边缘粗糙度和与图像传感器的距离。
Abstract In this article, we will explore the use of several spatial-domain focus metrics frequently applied in non-coherent (classical) imaging systems, and evaluate their suitability for the automated numerical focusing of marine holograms such as those collected with eHoloCam, the underwater digital holographic camera developed at Aberdeen University. Metrics will be applied to a set of particle holograms chosen to represent a range of features within the three categories: opacity, edge roughness and distance from image sensor.
