字節EX-4D 技術實現單目視頻4D化，解鎖極端視角下高質量內容生成
由研究團隊 tau-yihouxiang 開發的 EX-4D（Extreme Viewpoint4D Video Generation）技術，一項顛覆傳統的視頻生成創新，正在全球範圍內引發廣泛關注。這項技術旨在將單目視頻轉化爲可控的4D 體驗，尤其在極端攝像機角度下展現出卓越的性能。EX-4D 技術的核心在於其獨特的“深度水密網格”構建方法。這種新穎的幾何表示方式，能夠有效建模可見和被遮擋區域，並在 -90° 至90° 的廣泛角度範圍內生成高質量視頻。這一突破爲遊戲、電影製作、虛擬現實（VR）和增強現實(AR)等多個領域的應用奠定了基礎。
