Accurate and rapid detection of B-lines—vertical hyperechoic artifacts in lung ultrasound (LUS) images—is essential for diagnosing and monitoring pulmonary diseases. We propose a novel algorithm based on variational mode decomposition (VMD) for automatic segmentation and quantification of B-lines in LUS frames, marking the first application of VMD in this context. Each frame is treated as a 2-D signal and decomposed into intrinsic frequency modes, isolating characteristic vertical structures while suppressing…
