Dynamic reserve design with the union-find algorithm
收藏 引用
ECOLOGICAL MODELLING 2008年 第4期215卷 369-376页
作者: Harrison, Paul Spring, Daniel MacKenzie, Michael Mac Nally, Ralph Monash Univ Australian Ctr Biodivers Sch Biol Sci Clayton Vic 3800 Australia Monash Univ Victorian Bioinformat Consortium Clayton Vic 3800 Australia RMIT Univ Sch Econ Finance & Mkt Fac Business Melbourne Vic 3000 Australia
When reserve networks are established over time, there is a risk that sites will be developed in areas planned for future reservation, reducing the effectiveness of reserves. We developed a dynamic reserve design mode... 详细信息

PATTERN ANALYSIS AND APPLICATIONS 2009年 第2期12卷 117-135页
作者: Wu, Kesheng Otoo, Ekow Suzuki, Kenji Univ Calif Berkeley Lawrence Berkeley Natl Lab Berkeley CA 94720 USA Univ Chicago Dept Radiol Chicago IL 60637 USA
We present two optimization strategies to improve connected-component labeling algorithms. Taking together, they form an efficient two-pass labeling algorithm that is fast and theoretically optimal. The first optimiza... 详细信息
