创纪录的高速旋转磁体可能有助于揭示新物理现象
创纪录的高速旋转磁体可能有助于揭示新物理现象模拟雨景同时生成路面积水和反光
给街景加上几道雨丝，未必能重现摄像机在真实雨天看到的情况。街道上的水洼、倒影与路面几何位置相关，处理不当会让本来清楚的场景边界发生变化。CascadeRS团队将深度和语义分割信息用于生成雨景，在保持原场景结构的同时加入雨丝、湿表面反射和积水，并可控制合成效果。 Melissa Tijink等人的这项研究收录在11月6日更新的计算机科学预印本列表中。
研究者通过用户观察研究和定量指标评估合成画面的真实感，又以城市街景为基础制作了Cityscapes-CascadeRS数据集，用来研究计算机视觉模型在真实雨天任务中的表现。团队公开了代码和数据。这样，研究人员可以从同一张原图出发改变雨天效果，比较下游系统对雨丝、反光和积水的反应。视觉上逼真与模型在真实道路上可靠，仍是需要分别检验的两个问题。
