Abstract

Technologies to predict human actions are extremely important for applications such as human robot cooperation and autonomous driving. However, a majority of the existing algorithms focus on exploiting visual features of the videos and do not consider the mining of relationships, which include spatial relationships between human and scene elements as well as causal relationships in temporal action sequences. In fact, human beings are good at using spatial and causal relational reasoning mechanism to predict the actions of others. Inspired by this idea, we proposed a Spatial and Causal Relationship based Graph Reasoning Network (SCR-Graph), which can be used to predict human actions by modeling the action-scene relationship, and causal relationship between actions, in spatial and temporal dimensions respectively. Here, in spatial dimension, a hierarchical graph attention module is designed by iteratively aggregating the features of different kinds of scene elements in different level. In temporal dimension, we designed a knowledge graph based causal reasoning module and map the past actions to temporal causal features through Diffusion RNN. Finally, we integrated the causality features into the heterogeneous graph in the form of shadow node, and introduced a self-attention module to determine the time when the knowledge graph information should be activated. Extensive experimental results on the VIRAT datasets demonstrate the favorable performance of the proposed framework., Comment: 10 pages, 6 figures

Abstract

Rapid search and rescue responses after earthquakes or in postseismic evaluation tend to be extremely difficult. To solve this problem, we summarized the requirements of search and rescue rotary-wing unmanned aerial vehicle (SR-RUAV) systems according to related works, manual earthquake search and rescue, and our knowledge to guide our research works. Based on these requirements, a series of research and technical works have been conducted to present an efficient SR-RUAV system. To help rescue teams locate interested areas quickly, a collapsed-building detecting approach that integrates low-altitude statistical image processing methods was proposed, which can increase survival rates by detecting collapsed buildings in a timely manner. The entire SR-RUAV system was illustrated by simulated earthquake response experiments in the China National Training Base for Search and Rescue (CNTBSR) from 2008 to 2010. On April 20, 2013, Lushan (China) experienced a disastrous earthquake (magnitude 7.0). Because of the distribution of buildings in the rural areas, it was impossible to implement a rapid search and postseismic evaluation via ground searching. We provided our SR-RUAV to the Chinese International Search and Rescue Team (CISAR) and accurately detected collapsed buildings for ground rescue guidance at low altitudes. This system was significantly improved with respect to its searching/planning strategy and vision-based evaluation in different environments based on the lessons learned from actual missions after the earthquake. The SR-RUAV has proved to be applicable and time saving. The physical structure, searching and planning strategy, image-processing algorithm, and improvements in real missions are described in detail in this study. [ABSTRACT FROM AUTHOR]

31. Person re-identification using view-dependent score-level fusion of gait and color features.

Author

Abstract

This paper describes a method for person reidentification across multiple non-overlapping cameras using both gait and color features. Because a single color feature is insufficient to distinguish persons with similar color clothes, a spatio-temporal histogram of oriented gradients is employed as a gradient-based shape and motion gait feature to discriminate such persons in conjunction with a background edge attenuation technique. However, since the gait feature is more sensitive to view differences than the color feature, a view-dependent score-level fusion framework adaptively controls the weights of the gait and color features. Experiments across seven non-overlapping cameras confirm the effectiveness of the proposed method. [ABSTRACT FROM PUBLISHER]

Abstract

The elementary and secondary schools in the city of Laohekou, Hubei Province, have begun to review teachers in accordance with the "Trial Regulations Regarding the Professional Titles of Elementary and Secondary School Teachers" formulated by the State Education Commission. Teachers attach great importance to this matter. Some schools, however, charge teachers under evaluation fees, ranging from 20 to 50 yuan or more, and they arbitrarily deduct the money from the teachers' salaries. Such practices have aroused much controversy and complaints among the teachers. Some say: "This is not professional review. They are only collecting money!"
