復旦、百度聯手打造全新AI模型Hallo2 可生成4K超高清+1小時超長視頻！
復旦大學和百度公司的研究人員聯合開發了一種名爲 Hallo2的全新 AI 模型，該模型可以生成長達數小時的4K 分辨率人物動畫，並且可以通過語音和文字提示進行精準控制。一直以來，生成高質量的人物動畫需要耗費大量的時間和人力成本。而 Hallo2的出現，有望徹底改變這一現狀，爲電影製作、虛擬助手、遊戲開發等領域帶來革命性的變化。Hallo2模型建立在 latent diffusion models 的基礎上，並引入了一系列創新性的技術，包括:Patch-drop 數據增強技術:通過對運動幀進行隨機遮擋，防止模型過度依
