Abstract

Field of views of a slide are examined to assess the likelihood of existence of detectable single cells, groups, and thick groups of cells to locate objects of interest by an automated microscope. The FOV features consists of features selected from the distribution profiles of size, shape, layout arrangement, texture and density of all objects within a FOV which are compared against pre-determined criteria. Each field of view is assigned a likelihood value based on FOV features. Areas that are blank, or contain air bubbles, or are too dense for analysis are identified and excluded for further analysis. Each FOV is ranked according to its likelihood of containing SIL (Squamous Intraepithelial Lesion) cells or cell groups of interest. These results, such as SIL, single cell ranking, group ranking are used to arrange the further examination of FOVs in a priority order.
