Blob Detector ============= The :class:`BlobDetector` finds transient acoustic events in a spectrogram by computing local 2-D variance, binarising the result against a threshold, and tracing connected regions using Moore's Neighbourhood algorithm. Detections are filtered by minimum duration and bandwidth before being returned as an :class:`~ecosound.core.annotation.Annotation` object. .. autoclass:: ecosound.detection.blob_detector.BlobDetector :members: :undoc-members: :show-inheritance:
