چکیده

Feature Pyramid Networks (FPN) have become a standard multi-scale representation for modern visual recognition. This review consolidates core FPN design principles-top-down pathways, lateral fusion, and scale-aware heads and synthesizes recent variants such as BiFPN, PANet/PAFPN, ssFPN, Refine-FPN, and attention-guided fusion. We examine how these necks integrate with common backbones and detectors, summarize typical training setups and datasets (e.g., COCO, DOTA, SIRST), and report qualitative benefits frequently claimed in the literature, including improved small-object sensitivity, faster convergence, and better robustness to scale variance. Beyond natural images, we highlight applications in specialized domains (remote sensing, infrared, underwater), noting when patterns plausibly translate to medical image analysis. A functional comparison of representative detectors clarifies pipeline choices, loss designs, and computational trade-offs. We conclude with open challenges reliable gains across backbones, practical deployment under resource constraints, and standardized evaluation for domain transfer-and provide curated tables that connect variants to tasks, detectors, and the corresponding canonical references.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
