select op• Data kinds: labels2d → labels2d
• Call: import fullseye as fs; fs.ledger.blob_select_largest(labels: 'Any', count: 'int' = 1) -> 'np.ndarray' (to call the implementation directly, import blob2d; blob2d.blob_select_largest(labels: 'Any', count: 'int' = 1) -> 'np.ndarray'; from the registry, opsblob.get("blob_select_largest"))
Keeps only count objects in order of decreasing area (the numbers are reassigned in descending order of area).
When areas tie, the one with the smaller original number comes first (argsort is fixed to a stable sort so the order does not change between runs). Even if count exceeds the number of objects, whatever exists is returned (falling short is not an exception -- asking for "the top 3" and getting only 2 is not an anomaly).
