• 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 ...
  • 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 ...
