Uses the USGS Watershed Boundary Dataset and the 2010 US Census data to create representational voting districts with equivalent population.

...Remote sensing and image processing tasks include image enhancement (e.g. panchromatic sharpening, contrast adjustments), image mosaicing, numerous filtering operations, simple classification (k-means), and common image transformations. WhiteboxTools also contains advanced tooling for spatial hydrological analysis (e.g. flow-accumulation, watershed delineation, stream network analysis, sink removal), terrain analysis (e.g. common terrain indices such as slope, curvatures, wetness index, hillshading; hypsometric analysis; etc.

Software that allows you to manually and quickly annotate images in directories. The method is pseudo manual because it uses the algorithm watershed marked of OpenCV. The general idea is to manually provide the marker with brushes and then to launch the algorithm. If at first pass the segmentation needs to be corrected, the user can refine the markers by drawing new ones on the erroneous areas.

This page shows the cell segmentation/tracking program for FUNseq pipeline. Identifying a sparse subset of cancer cells from a large heterogeneous population, based on aggressive phenotypes (like invasive migration, multipolar divisions, or asymmetric lineage development) is challenging. Also, such aberration identification is critical, as cells exhibiting these characteristics are linearly correlated with poor prognosis. A high-throughput screening microscope has been developed in our...

SegmentIt is an interactive image segmentation tool that allows to switch back and forth between the watershed approaches (watershed from markers and hierarchical watershed) so the user can explore the strengths of both.

...Because it’s small and self-contained, it’s often used as a reference to understand the vulnerability mechanics without wading through large codebases. The repo also serves as a historical snapshot of a watershed moment in modern Internet security and the practical lessons it forced the industry to learn. Developers and security engineers alike can study it to better appreciate protocol hardening, input validation, and defense-in-depth strategies.

GeoSolid3D produces 3D geologic solid models, incorporated into the aquifer and confining units of the USGS ground water models, Modflow and Sutra. Uses GIS data of DEMs, geologic maps, and maps of river, watershed, recharge, and aquifer parameters.

C++ Library for Emergent Self-Organizing Maps

HWST stands for "Hierarchical Watershed Transformation" which is an image segmentation technique. The HWST library was designed for a comfortable use as a JAI operator (Java Advanced Imaging).
