U-Nets are fully convolutional neural networks known for their excellent performance in image segmentation. This talk discusses U-Nets for semantic segmentation of 1-, 2- and 3-dimensional data with application examples from remote sensing and medical data analysis. A general, lightweight system for efficient and accurate 3D image segmentation is discussed. It requires no task-specific information, almost no human interaction and is based on a fixed neural network topology and a fixed hyperparameter set, eliminating the need for model selection and its inherent tendency to cause overfitting. The talk also presents U-Time, a feed-forward network for physiological time series segmentation developed for the analysis of sleep data. U-Time maps sequential inputs of arbitrary length to sequences of class labels on a freely chosen temporal scale. The presented systems are available open source and do not require deep learning expertise to use.
