To protect fragile paintings and calligraphy, Taiwan's National Palace Museum (NPM) has policies controlling the frequency and duration of their exposure. So, visitors might not see the works they planned to see. To address this problem, the NPM installed an interactive tabletop for viewing the works. This tabletop, the first to feature multiresolution and gigapixel photography technology, displays extremely high-quality images revealing brushwork-level detail. A user study at the NPM examined the tabletop's performance and collected visitor feedback. [ABSTRACT FROM AUTHOR]

Human behavior analysis is an important area of research in computer vision and is also driven by a wide spectrum of applications, such as smart video surveillance and human-computer interface. In this paper, we present a novel approach for human behavior analysis. Two research challenges, motion representation and behavior recognition, are addressed. A novel motion descriptor, which is an improved feature based on optical flow, is proposed for motion representation. Optical flow is improved with a motion filter, and feature fusion with the shape and trajectory information. To recognize the behavior, the support vector machine is employed to train the classifier where the concatenation of histograms is formed as the input features. Experimental results on the Weizmann behavior database and the Institute of Automation, Chinese Academy of Science real- world multiview behavior database demonstrate the robustness and effectiveness of our method.

The article focuses on the Chinese research and development in natural language technology. It discusses the cognitive process of natural language understanding (NLU) in a human brain. It explores the aspects of text and speech as the two basic attributes of human language. It discourses the implementation of practical natural language processing (NLP) systems oriented to perform specific tasks, defined as the discipline that studies the linguistic aspects of human-human and human-machine communication. It notes that the technical terms such as the NLU and NLP can be simplified as natural language technology (NLT), since they address the same issues. It highlights the fruitful advances of the NLT in China.
