Description of the biological application

Segmenting nuclei in 3D images can be challenging especially when nuclei are clustered and have different intensity. This image set contains a clustered monolayer of nuclei that can be difficult to segment and is provided along with manually annotated ground truth that can be used for image analysis software testing purposes.

Edge and center regions of the same cell colony can have different morphology and intensity. Analysis of 3D images can provide a complete picture of such differences. Two of the image sets contain clustered monolayer of cells at the edge and center of the hiPSC colony.

Images

Images were obtained by using Zeiss AxioObserver microscope with C-Apochromat 100x/1.25 water immersion objective and Hamamatsu ORCA-Flash 4.0 camera.
