pyXenium.contour.summarize_contour_topology

summarize_contour_topology(sdata, *, contour_key, contour_query=None, groupby=None, boundary_tolerance=1.0, min_shared_boundary=0.0, enclosure_min_fraction=0.95, histoseg_root=None)

Summarize contour boundary-neighbor and enclosure relationships.

This is a thin pyXenium wrapper around HistoSeg’s pure-geometry topology engine. It reconstructs one Shapely geometry per contour from sdata.shapes[contour_key] and returns plain pandas tables.

Parameters:

• sdata (XeniumSlide)

• contour_key (str)

• contour_query (str | None)

• groupby (str | None)

• boundary_tolerance (float)

• min_shared_boundary (float)

• enclosure_min_fraction (float)

• histoseg_root (str | Path | None)

Return type:

dict[str, DataFrame]
