近年来，随着 VR 头戴设备、智能眼镜、3D 影院的发展，人们对于 3D 立体视频内容的需求不断增加。3D 电影带来的沉浸式体验着实令人着迷，但因其 制作过程需要专业的相机设备、复杂耗时的专家后处理，3D 内容的制作让普通玩家望而却步： 2010 年，卡梅隆导演为了实现经典著作《泰坦尼克号》的 3D 版本重制， 制作团队投入了高达 1800 万美元，动用了 300 名专业工程师，耗时整整 60 周才完成 [1]。 如此高昂的成本和复杂的人力投入，一直是 3D 内容生产的最大阻碍。尽管近年来自动化的 "单目转双目"（Monocular-to-Stereo） 技术有所发展，但效 果往往不尽如人意，转换的结果往往要么产生错误的视差，要么无法处理复杂的镜面场景，且速度极慢：现有的研究工作转换一段 5 秒的视频，耗时 15 分 钟到 70 分钟不等 。 针对这一难题， 快手可灵团队与香港科技大学（广州）陈颖聪教授团队（共同一作博士生沈贵宝、红鸟硕士生杜壹华、博士生葛汶杭） 联合提出了一种全 新的解决方案 ——StereoPilot。这是一种基于生成式先验的统一高效立体视频转换模型， 能够在极短的时间内（11 秒） ，将 ...

Core Viewpoint - The article discusses the challenges and advancements in bi-directional video coding, particularly focusing on the new BRHVC method developed by Kuaishou's audio and video technology team, which significantly improves compression performance over existing standards [2][29]. Video Coding Challenges - Video coding is essential for addressing the conflict between massive video data and limited transmission and storage resources, with uncompressed 4K video reaching up to 20 GB per minute [4]. - Current video coding techniques can reduce video bitrate by 1/100 to 1/1000, enabling applications like short videos, live streaming, and cloud gaming [4]. Bi-directional Coding - Bi-directional coding (RA mode) has been a "secret weapon" for efficient compression but faces challenges in deep learning-based intelligent video coding due to complex reference structures [2][7]. - The RA mode can save over 20% bitrate compared to low-latency modes while maintaining high quality, making it suitable for on-demand and storage scenarios [7]. Key Issues in RA Mode - The long-span frame motion processing is complicated due to the exponential growth of frame intervals, which can reach up to 32 frames, leading to significant motion complexity [8]. - There is a notable imbalance in the contribution of reference frames, where the value of information from two reference frames can differ significantly, affecting encoding efficiency [9][11]. BRHVC Framework - The BRHVC framework introduces two innovative modules: Bi-directional Motion Converge (BMC) and Bi-directional Contextual Fusion (BCF), addressing the challenges of long-span motion processing and reference contribution imbalance [13][20]. - BMC enhances motion estimation by aggregating multi-scale optical flow into a single latent variable, improving motion compensation accuracy in large displacement scenarios [16][17]. - BCF generates spatially adaptive weight maps to re-weight reference features based on their importance, effectively addressing occlusion issues in long-span frames [20][22]. Experimental Results - BRHVC achieved an average bitrate saving of 32.0% compared to traditional encoders like VTM-LDB, with a peak saving of 44.7% in Class D sequences [25]. - The framework also surpassed the VTM-RA encoder in encoding efficiency, demonstrating its effectiveness in bi-directional intelligent video compression [25]. Conclusion - The research highlights the core challenges in bi-directional intelligent video compression and presents the BRHVC framework as a significant advancement, providing a new direction for future developments in intelligent video coding [29].
