Because automatic algorithms do not correctly segment all nuclei in tissue sections, interactive algorithms may be preferable for some applications. ...
Existing interactive segmentation algorithms require the analyst to draw a border around the nucleus under consideration in all successive two-dimensional (2D) planes of the 3D image. ...
Therefore a single, 6-connected 3D binary erosion was applied to the segmented objects. This application made FN Ͼ FP for some objects and FP Ͼ FN for others. ...
