Abstract：
如今，数十亿的视频数据在云端被捕获，托管和共享，世界已进入多媒体大数据时代。作为一个活跃的跨学科研究领域，多媒体大数据为大数据计算带来了挑战和机遇。针对大数据分析的不同方向，专家们已经在图像处理上进行了大量的研究工作，例如捕获，存储，索引，挖掘和检索等操作。然而，由于需要考虑视频数据的空间和时间特征，视频处理更具挑战性。在本次演讲中，何文波教授把重点放在视频大数据计算上，阐述从图像数据转向视频数据计算时的挑战。在讲座的后半部分，何文波教授将讨论视频大数据分析中的应用程序和潜在的未来方向，例如近似重复视频检测技术，它通过少量的学习样本进行动作识别，融合了视觉内容和文本内容。
Nowadays, billions of videos are captured, hosted and shared in the cloud, and the world has stepped into a multimedia big data era. As an active and interdisciplinary research field, multimedia big data presents challenges and opportunities for multimedia big data computing. A vast amount of research work has been done in image processing, targeting different aspects of big data analytics, such as the capture, storage, indexing, mining, and retrieval. However, the video processing is much more challenging since both spatial and temporal features of video data need to be considered. In this talk, I will focus on video big data computing, I will illustrate the challenges when we move from image data to video data computing. Then I will talk about applications and the potential future directions in video big data analytics, such as near-duplicated video detection, action recognition with very small learning samples, and information fution of visual and textual contents.
