在科技界，人才的流动往往预示着行业的风向变化。近日，谷歌研究院的Omer Bar-Tal博士宣布加盟Pika，担任该公司的创始科学家。这一消息在业界引起了不小的轰动。Bar-Tal博士在谷歌的研究生涯虽然短暂，但他的贡献却不容小觑。在谷歌的9个月期间，他作为Student Researcher参与了Lumiere项目的研发，并最终以共同第一作者的身份推出了这一革命性的视频生成技术。
Lumiere项目的核心创新在于其提出的时空U-Net（STU-Net）架构。这一架构允许视频在空间和时间两个维度上同时进行下采样和上采样，从而在网络的中间层得到视频的压缩时空表示。这一技术在学习了超过3000万视频之后，已经能够支持文生视频、视频编辑修复、图片转视频以及视频风格化等多种功能，极大地扩展了视频生成技术的应用范围。
Bar-Tal博士的加盟，无疑为Pika注入了强大的技术力量。作为一家专注于视频生成技术的新兴公司，Pika有望在Bar-Tal博士的带领下，进一步推动视频生成技术的创新和发展。

In the world of technology, the movement of talent often indicates the direction of the industry. Recently, Omer Bar-Tal, a researcher from Google’s Institute, announced his joining of Pika as a founding scientist, causing a stir in the industry. Although Bar-Tal’s research career at Google was brief, his contributions were significant. During his 9-month tenure as a Student Researcher, he participated in the development of the Lumiere project and ultimately released this revolutionary video generation technology as a co-first author.
The core innovation of the Lumiere project lies in its proposed Spatiotemporal U-Net (STU-Net) architecture, which allows video to be downsampled and upsampled in both spatial and temporal dimensions, resulting in a compressed spatiotemporal representation in the middle of the network. After learning from over 30 million videos, this technology can now support text-to-video, video editing and repair, image-to-video, and video stylization, greatly expanding the application scope of video generation technology.
