      <title>Holo-World: Unified Camera, Object and Weather Control for Video World Model</title>

      <description>&lt;p&gt;本文提出Holo-World，一种统一的视频世界模型，可从单张图像出发，联合控制相机运动、物体动态和天气状态。作者构建了HoloStateData数据集，将多样视频转换为统一控制样本；并提出统一场景适配器，将世界保持与天气迁移分解到不同参数子空间，利用渲染背景、几何缓冲和物体控制维持场景结构，同时建模天气相关外观与粒子效果。场景-天气分解CFG进一步分别引导场景和天气残差，增强目标天气效果。实验表明，Holo-World在保持精确控制的同时，实现了优于视频到视频基线的天气状态生成。&lt;/p&gt;

      <description>&lt;p&gt;本文提出RiO-DETR，一种面向实时旋转目标检测的DETR框架。针对方向语义依赖、角度周期性和搜索空间扩大等挑战，设计了内容驱动的角度估计、旋转校正正交注意力、解耦周期细化以及定向密集O2O机制，在保持实时效率的同时提升角度收敛速度与检测精度。在DOTA-1.0、DIOR-R和FAIR-1M-2.0上的实验表明，该方法实现了新的速度-精度平衡。&lt;/p&gt;
