摘要： Cell based assays are used to assess the hepatotoxicity of a stimulus. Imaging technologies are used to analyze the effects of a stimulus on hepatocytes. Image analysis may characterize the stimulus on the basis of whether it is hepatotoxic, and if so what type of pathology is exhibited; e.g., apoptosis, necrosis, cholestasis, and/or steatosis.

摘要： An image analysis method characterizes cells based on the elongation. It analyzes an image of the cells and automatically identifies points or locations of high contrast (i.e., regions where the transition from intense signal to weak signal occurs abruptly, over a short distance). Groups of contiguous high contrast points collectively define a putative cell edge. Identified edges are then analyzed to determine whether they are elongated. In one example, edges with relatively low curvature are deemed elongated. The curvature analysis may be accomplished by calculating a shape descriptor for each edge (e.g., calculating the circular variance for each edge). One or more stages of the analysis may employ some degree of filtering, smoothing or other processing to remove certain artifacts in the image.
摘要翻译：图像分析方法基于伸长率来表征细胞。它分析单元格的图像，并自动识别高对比度的点或位置（即从短时间内突然发生从强信号到弱信号的转变的区域）。连续的高对比度组的组合共同定义推定的细胞边缘。然后分析识别的边缘以确定它们是否伸长。在一个示例中，具有相对低曲率的边缘被认为是伸长的。可以通过计算每个边缘的形状描述符（例如，计算每个边缘的圆形方差）来实现曲率分析。分析的一个或多个阶段可以采用某种程度的滤波，平滑或其他处理来去除图像中的某些伪影。

摘要： Methods, data processing apparatus and computer program products for characterising cells and the affect of treatments administered to cells are disclosed. In particular methods of identifying bi-nuclear cells are described which include capturing an image of a plurality of marked cells and processing image to obtain features of the plurality of cells. The features are analyzed to determine whether the feature is indicative of bi-nuclear cells. Those cells for which the first feature is indicative of bi-nuclear cells are identified as being bi-nuclear. Three algorithms in particular are described. A first algorithm can be used to determine the number of nuclei in an image of a nuclear component by determining the number of concave regions within the outline of the image. A second algorithm uses a measure of the amount of cytoplasmic material between a pair of nuclei to identify bi-nuclear cells. A third algorithm uses the statistics of the spatial distribution of objects to identify isolated pairs of nuclei which can be considered to be from the same cell.
