shoot.eddies.associate.BiMod

class shoot.eddies.associate.BiMod(eddies, ref_eddies, dmax)

Bipartite matching for eddy association with validation metrics

Performs eddy association and computes validation metrics including match proportion, area overlap, and distance between matched eddies.

Parameters:

• eddies (Eddies2D) – Eddies to associate with reference.

• ref_eddies (Eddies2D) – Reference eddies for comparison.

• dmax (float) – Maximum distance (km) for association.

pmatch

Proportion of eddies that match with reference (property).

Type:

float

parea

Average intersection area ratio between matched eddies (property).

Type:

float

dist

Average distance (km) between matched eddy centers (property).

Type:

float

__init__(eddies, ref_eddies, dmax)

Initialize bipartite matcher

Parameters:

• eddies (Eddies2D) – Eddies to associate with reference.

• ref_eddies (Eddies2D) – Reference eddies for comparison.

• dmax (float) – Maximum distance (km) for association.

Methods

compare(eddies, ref_eddies[, max_distance])

add id to ref eddies and associate eddies to this ids when possible

Attributes

dist	Average distance between matched eddy centers
