segmantR (development version)

Bug fixes

• sg_segment_threshold(method = "adaptive") no longer errors with “replacement has length zero”. The internal integral-image lookup now treats out-of-range indices as contributing zero, so adaptive thresholding works for all images.

segmantR 0.1.0

• Initial release.
• Classical segmentation: adaptive thresholding, watershed, Voronoi propagation.
• Deep learning wrappers: Cellpose, StarDist, Mesmer (via reticulate).
• Human-in-the-loop annotation and correction workflow.
• Custom model training and portable model export (.segmantR archives).
• Feature extraction: intensity, morphology, texture, location.
• Shiny application with six tabs for interactive segmentation workflows.
• Export to GeoJSON, QuPath, CSV, SpatialExperiment.
• Bundled synthetic sample data for demonstrations.
