This article presents a systematic analysis of focus functions in conventional sputum smear microscopy for tuberculosis. This is the first step in the development of automatic microscopy. Nine autofocus functions are analyzed in a set of 1200 images with varying degrees of content density. These functions were evaluated using quantitative procedures. The main accomplishment of this work was to show that an autofocus function based on variance measures produced the best results for tuberculosis images.
本文对传统痰涂片显微镜检查中用于结核病的聚焦功能进行了系统分析。这是自动显微镜开发的第一步。在一组1200张内容密度不同的图像中分析了九种自动聚焦功能。这些功能通过定量程序进行评估。这项工作的主要成果是表明基于方差测量的自动聚焦功能在结核病图像上产生了最佳结果。
