• Activity Analysis, Summarization, and Visualization for Indoor Human Activity Monitoring 

    Zhou, Zhongna; Chen, Xi; Chung, Yu-Chia, 1979-; He, Zhihai, 1973-; Han, Tony X.; Keller, James M. (IEEE, 2008-11)
    In this work, we study how continuous video monitoring and intelligent video processing can be used in eldercare to assist the independent living of elders and to improve the efficiency of eldercare practice. More ...
  • Adaptive Silhouette Extraction and Human Tracking in Complex and Dynamic Environments 

    Chen, Xi; He, Zhihai, 1973-; Anderson, Derek T., 1979-; Keller, James M.; Skubic, Marge (IEEE, 2006-10)
    Extracting a human silhouette from an image is the enabling step for many high-level vision processing tasks, such as human tracking and activity analysis. Although there are a number of silhouette extraction and human ...
  • Adaptive Silhouette Extraction In Dynamic Environments Using Fuzzy Logic 

    Chen, Xi; He, Zhihai, 1973-; Keller, James M.; Anderson, Derek T., 1979-; Skubic, Marge (IEEE, 2006-07)
    Extracting a human silhouette from an image is the enabling step for many high-level vision processing tasks, such as human tracking and activity analysis. In a previous paper, we addressed some of the challenges in ...
  • Automated Estimation of Elder Activity Levels from Anonymized Video Data 

    Harvey, Nicholas M.; Zhou, Zhongna; Keller, James M.; Rantz, Marilyn J.; He, Zhihai, 1973- (IEE, 2009-09)
    Significant declines in quality of life for elders in assisted living communities are typically triggered by health events. Given the necessary information, such events can often be predicted, and thus, be avoided or reduced ...
  • A Real-time System for In-home Activity Monitoring of Elders 

    Zhou, Zhongna; Dai, Wenqing, 1984-; Eggert, Jay; Giger, Jarod T.; Keller, James M.; Rantz, Marilyn J.; He, Zhihai, 1973- (IEEE, 2009-09)
    In this paper, we propose a real-time system for in-home activity monitoring and functional assessment for elder care. We describe the development of the whole system which could be used to assist the independent living ...
  • Recognizing Falls from Silhouettes 

    Anderson, Derek T., 1979-; Keller, James M.; Skubic, Marge; Chen, Xi; He, Zhihai, 1973- (IEEE, 2006-08)
    A major problem among the elderly involves falling. The recognition of falls from video first requires the segmentation of the individual from the background. To ensure privacy, segmentation should result in a silhouette ...
