RodinHD：可根據肖像生成高保真3D頭像模型 頭髮細節也有了
RodinHD技術革新3D頭像生成，依據肖像照片創造高保真3D角色，尤其是在頭髮細節處理上實現突破。其核心在於獨創的三平面擬合與生成框架，包括爲每個角色定製高解析三平面和配置共享解碼器，以及通過學習基本與上採樣模型的級聯來生成細節豐富的高分辨率三平面。針對解碼器在連續擬合過程中的遺忘問題，RodinHD引入了任務重放的數據調度策略和權重合並正則化項，優化了對新角色細節的捕捉與呈現能力。
此外，通過優化噪聲調度和使用預訓練的變分自編碼器進行多尺度特徵表示計算，RodinHD確保了細節完整保留，並在46000個頭像的訓練下表現卓越，生成的3D角色在細節上超越傳統技術，適應各種野外地像輸入，全面革新了現有3D化身生成技術。
