It is designed for object-based image analysis (OBIA) workflows on large raster datasets, including satellite and aerial imagery. The core focus is on producing spatially coherent, integer-labeled segment rasters that integrate cleanly with downstream raster and vector analysis in R. Key Features Graph-based and hybrid segmentation algorithms: Includes Fast Felzenszwalb-Huttenlocher (FH) graph-based segmentation, Hybrid FH + region-level Mean Shift segmentation, Baatz-Schäpe multi-resolution, Fast Baatz-Schäpe multi-resolution, and SEEDS.
