Unique: Overlapping patch embeddings (vs non-overlapping in ViT) enable smoother feature transitions across scales, reducing boundary artifacts; hierarchical design with 4 scales balances efficiency (B0 is lightweight) with expressiveness

vs others: More efficient multi-scale processing than FPN-based models (ResNet+FPN) because transformer self-attention naturally captures multi-scale context without explicit feature pyramid construction
