A computationally efficient method for delineating irregularly shaped spatial clusters
In this paper, we present an efficiency improvement for the algorithm called AMOEBA, A Multidirectional Optimum Ecotope-Based Algorithm, devised by Aldstadt and Getis (Geogr Anal 38(4):327–343, 2006). AMOEBA embeds a local spatial autocorrelation statistic in an iterative procedure in order to identify spatial clusters (ecotopes) of related spatial units. We provide an analysis of the computati...
متن کاملAdaptations for finding irregularly shaped disease clusters
BACKGROUND Recent adaptations of the spatial scan approach to detecting disease clusters have addressed the problem of finding clusters that occur in non-compact and non-circular shapes--such as along roads or river networks. Some of these approaches may have difficulty defining cluster boundaries precisely, and tend to over-fit data with very irregular (and implausible) clusters shapes. RESU...
متن کاملAutomatic Modelling Method for Steel Structures Using Photogrammetry
Industrial Photogrammetry which has advantages of high accuracy and fast measurement time is widely used in the manufacture measurement application. Especially, industrial photogrammetry has more powerful capability of quickness in the 3 dimensional coordinate measurement then comparing with optical measurement system like total station, laser tracker and laser scanner. The purpose of this pape...
متن کاملStarScan: A Novel Scan Statistic for Irregularly-Shaped Spatial Clusters
Introduction Kulldorff’s spatial scan statistic1 detects significant spatial clusters of disease by maximizing a likelihood ratio statistic over circular spatial regions. The fast localized subset scan2 enables scalable detection of proximity-constrained subsets and increases power to detect irregularly-shaped clusters, However, unconstrained subset scanning within each circular neighborhood2, ...
متن کاملA binary-based approach for detecting irregularly shaped clusters
BACKGROUND There are many applications for spatial cluster detection and more detection methods have been proposed in recent years. Most cluster detection methods are efficient in detecting circular (or circular-like) clusters, but the methods which can detect irregular-shaped clusters usually require a lot of computing time. METHODS We propose a new spatial detection algorithm for lattice da...
