# evo-mars-clustering-eval

Core clustering and evaluation utilities for DBSCAN-based Mars cloud annotation clustering.

## Key Functions

- `weighted_euclidean_pairwise(u, v, w)` - Custom distance: sqrt((w*dx)^2 + ((2-w)*dy)^2)
- `compute_precomputed_distance_matrix(X, w)` - Build precomputed distance matrix for DBSCAN
- `run_dbscan_and_get_centroids(X, eps, min_samples, dist_matrix)` - Run DBSCAN, return centroids
- `greedy_match(centroids, ground_truth, threshold=100.0)` - Greedy bipartite matching
- `score_image(citsci_points, expert_points, eps, min_samples, w)` - Full per-image scoring

## Usage
