格隆匯 8 月 20日丨衞寧健康(300253.SZ)公佈,公司於近日取得國家知識產權局頒發的一項發明專利證書,涉基於深度學習及影像組學的骨齡標記識別評估方法及系統。

該發明公開了一種基於深度學習及影像組學的骨齡標記識別評估方法及系統,其中骨齡標記識別方法包括:對手腕部骨骼影像進行調窗、對齊、標準化的預處理;用bounding box標記出骨齡特徵區域並記錄座標,骨齡特徵區域包括符合TW3法的掌指骨羣和腕骨羣;根據需要增廣處理,同時輸入到基於ResNet-101的區域的卷積神經網絡中進行多任務(定位、分類、評估)訓練;基於骨齡特徵區域結合臨牀信息(人口統計特徵,檢查報告)進一步訓練提升骨齡評估速度及準確率。本發明先利用少量已標記樣本對骨齡模型初步訓練,並利用較高定位檢測精度的模型對大量樣本進行自動標記從而實現了自動化骨齡特徵區域定位、分類和骨齡評估。

上述發明專利技術目前已應用於公司產品,專利的取得不會對公司目前經營產生重大影響,但有利於進一步完善公司知識產權保護體系,發揮自主知識產權優勢,提升公司的核心競爭力。
