论文摘要
在本文中，我们提出了一个适合自动焦点措施分析的新型热力计图像数据库。该数据库由8个不同的场景组成，每个场景都包含一个用于96个不同焦点位置的图像。使用此数据库，我们评估了六个焦点措施的实用性，以确定最佳焦点位置。实验结果表明，即使计算负担较低，也可以准确地自动检测最佳聚焦位置。我们还提出了一种能够帮助获取热图像的采集工具。据我们所知，这是关于热图像自动焦点的首次研究。
In this paper we present a new thermographic image database suitable for the analysis of automatic focus measures. This database consists of 8 different sets of scenes, where each scene contains one image for 96 different focus positions. Using this database we evaluate the usefulness of six focus measures with the goal to determine the optimal focus position. Experimental results reveal that an accurate automatic detection of optimal focus position is possible, even with a low computational burden. We also present an acquisition tool able to help the acquisition of thermal images. To the best of our knowledge, this is the first study about automatic focus of thermal images.
