Abstract

Digital technology has taken a prominent place today in microscopy, whether in the field of materials sciences, medicine or biology.The use of deep learning approaches has become an essential solution in the processing and analysis of big data acquired in microscopy. They allow their classification or their modeling on the basis of statistical laws, and can also assist us in decision-making and the visualization of these data. “Ad hoc” algorithms and “deep learning” approaches have demonstrated in recent years their ability to be able to help decision-making on the acquisition parameters to be chosen and even in some cases replace the operator. For example, analyzing images during the acquisition can help decide what to do next and guide the microscope, or allow you to search for rare events automatically. They also make it possible to extract information from the image that did not seem to be present, using a priori knowledge, formalized or not, as in the case of denoising, artifact correction or resolution improvement of the image.They are also able to extract phenotyping or characterization data automatically and without speed comparison with a human operator, with reproducible quantification bias, by segmentation, tracking, or analysis of signals and derived measurements. The development of these algorithms and in particular machine learning models for all these applications requires the sharing of annotated data in order to develop them, which also calls for new sharing and annotation solutions.
