Computer vision and machine learning software

  • CellCognition

    CellCognition is an open source software that combines object detection, classification of morphologies, and single-cell tracking. This enables measurements of progression through morphology stages and kinetic readouts at the single-cell level. The software was designed to run on three major platforms (Windows, Mac OS X, Linux) at high speed with high convenience. We therefore combined C++ image processing based on VIGRA with a Python-based workflow engine and a Qt-based graphical user-interface. To enable interoperability between different software platforms, we developed the standardized data exchange format CellH5, which stores high-dimensional image data along with inter-object relations in graphs. Please reference the CellCognition software by the original publication Held et al., Nature Methods, 2010.
