3D Cell Nuclei Segmentation with Balanced Graph Partitioning
Julian Arz, Peter Sanders, Johannes Stegmaier +1
Cell nuclei segmentation is one of the most important tasks in the analysis of biomedical images. With ever-growing sizes and amounts of three-dimensional images to be processed, t…
Generating Semi-Synthetic Validation Benchmarks for Embryomics
Johannes Stegmaier, Julian Arz, Benjamin Schott +6
Systematic validation is an essential part of algorithm development. The enormous dataset sizes and the complexity observed in many recent time-resolved 3D fluorescence microscopy…
LZ-Compressed String Dictionaries
Julian Arz, Johannes Fischer
We show how to compress string dictionaries using the Lempel-Ziv (LZ78) data compression algorithm. Our approach is validated experimentally on dictionaries of up to 1.5 GB of unco…
Transit Node Routing Reconsidered
Julian Arz, Dennis Luxen, Peter Sanders
Transit Node Routing (TNR) is a fast and exact distance oracle for road networks. We show several new results for TNR. First, we give a surprisingly simple implementation fully bas…
