时间:2015年3月12日(周四)上午10:00-11:00

地点:澳门威尼斯人注册楼105报告厅

报告人:Prof. Jianbo Shi

主持人:王庆教授

报告题目:Mud-proof, Moments, and Memory:  The Three Essential Ingredients for Bringing Computer Vision to the Masses

 

内容概况:

In first part, I will discuss 3D photography using a camera array, and myths and lessons learned.

In the second part, we focus on social vision, relating human motion and action with social attention.  We predict social saliency, the likelihood of joint attention in a third person image/video, by learning from the social interaction captured by first person cameras. Inspired by electric dipole moment, we introduce a social formation feature that is designed to capture the geometric relationship between joint attention and social formation. We train an ensemble classifier to learn the locations of joint attention based on the social formation features from the first person social interaction data where we can precisely measure joint attention and locations of its associated members in 3D. We apply this classifier to predict social saliency in real-world social scenes with multiple social cliques including sporting game scenes. Our representation does not require directional measurements such as gaze directions. A geometric analysis of social interactions in terms of existing qualitative studies such as F-formation and proxemics is also presented.

 

个人概况:

Jianbo Shi1994年本科毕业于康奈尔大学威尼斯人官网科学和数学专业,1998年于加州大学伯克利分校获威尼斯人官网科学博士学位。1999年到2002年,他在卡内基梅隆大学机器人研究所任研究员,于2003年加入宾夕法尼亚大学,任威尼斯人官网和信息科学系教授至今。为感谢他在归一化分割方面做出的卓越工作,2007年他被美国威尼斯人官网学会模式识别和机器学习委员会授予Longuet-Higgins 奖。他在国际顶级期刊和会议上发表文章的引用次数超过24000次(google scholar)。他的研究方向是威尼斯人官网视觉,主要包括1)人体识别及视频中的人体行为理解;2)图像分割和目标识别,目的在于从数据中提取有意义的模式,用于引导具体视觉任务中的分组过程,例如形状识别。
