This paper describes the application of a television-based system (LEYTAS) in machine analysis of cervical specimens. LEYTAS basically consists of a Leitz microscope, the texture analysis system (TAS, Leitz), a TV camera, a 4-bit grey value memory and a minicomputer (PDP 11/23). A series of 1176 Feulgen stained cervical smears has been analysed in an automated procedure using image transformation for cell selection and artefact rejection. During the analysis of the entire series new artefact rejection procedures have been added to the automated analysis. This addition decreased the percentage of false positives to 15% in the last 277 analysed smears. This percentage concerns machine performance alone. A rapid visual interaction procedure decreases this percentage to 9%. Out of 210 morphologically positive smears (diagnosis Papanicolaou class 3b or more) from the total series, one smear was missed by LEYTAS using the machine classification.
本文描述了一种基于电视的系统（LEYTAS）在宫颈标本机器分析中的应用。LEYTAS主要由一台徕卡显微镜、纹理分析系统（TAS，徕卡）、一台电视摄像机、一个4位灰度值存储器和一台小型计算机（PDP 11/23）组成。使用图像变换进行细胞选择和伪像剔除的自动化程序对1176份福尔根染色的宫颈涂片进行了分析。在对整个系列的分析过程中，新的伪像剔除程序被添加到自动化分析中。这一添加使得在最后分析的277份涂片中，假阳性百分比降至15%。该百分比仅涉及机器性能。快速视觉交互程序将该百分比降至9%。在整个系列的210份形态学阳性涂片（巴氏诊断3b级或更高）中，LEYTAS使用机器分类遗漏了一份涂片。
