Generalized nucleus segmentation techniques can contribute greatly to reducing the time develop and validate visual biomarkers for new digital pathology datasets. We summarize results of MoNuSeg 2018 Challenge whose objective was generalizable nuclei in pathology. The challenge an official satellite event MICCAI conference which 32 teams with more than 80 participants from geographically diverse institutes participated. Contestants were given a training set 30 images seven organs annotations...
Positional information is a central concept in developmental biology. In developing organs, positional can be idealized as local coordinate system that arises from morphogen gradients controlled by organizers at key locations. This offers plausible mechanism for the integration of molecular networks operating individual cells into spatially coordinated multicellular responses necessary organization emergent forms. Understanding how cues guide morphogenesis requires quantification gene...

Pre-eclampsia is a severe placenta-related complication of pregnancy with limited early diagnostic and therapeutic options. Aetiological knowledge controversial, there no universal consensus on what constitutes the late phenotypes pre-eclampsia. Phenotyping native placental three-dimensional (3D) morphology offers novel approach to improve our understanding structural abnormalities in Healthy pre-eclamptic tissues were imaged multiphoton microscopy (MPM). Imaging based inherent signal...

Automated image processing approaches are indispensable for many biomedical experiments and help to cope with the increasing amount of microscopy data in a fast reproducible way. Especially state-of-the-art deep learning-based most often require large amounts annotated training produce accurate generalist outputs, but they compromised by general lack those sets.

Recent microscopy imaging techniques allow to precisely analyze cell morphology in 3D image data. To process the vast amount of data generated by current digitized techniques, automated approaches are demanded more than ever. Segmentation used for morphological analyses, however, often prone produce unnaturally shaped predictions, which conclusion could lead inaccurate experimental outcomes. In order minimize further manual interaction, shape priors help constrain predictions set natural...
