A marked point process perspective in fitting spatial point process models

Journal of Statistical Planning and Inference, 2008
This paper discusses a new perspective in fitting spatial point process models. Specifically the spatial point process of interest is treated as a marked point process where at each observed event x a stochastic process M ( x ; t ) , 0 < t < r , is ...

Tests for Independence between Marks and Points of a Marked Point Process

Biometrics, 2005
Summary A convenient assumption while modeling a marked point process is that the observations (i.e., marks) and the locations (i.e., points) are independent. We propose new graphical and formal testing approaches to test for this assumption. The proposed graphical procedures are easy to obtain and can be used to diagnose the nature and range of ...

On Correlations of Marked Point Processes

Mathematische Nachrichten, 1984
The paper studies correlations of the marks of marked point processes in \(R^ d\). At first some results of the classical theory of marked point processes are refined. For the case of non-negative marks the mark-sum measure is studied. For a Borel set B it gives the sum of marks of all points in B. Then a mark covariance function is defined which gives

Crater detection based on marked point processes

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
A novel automatic method is developed for the detection of features in planetary images. Although many automatic feature extraction methods have been proposed for for remote sensing images of the Earth, these methods are typically unfeasible for planetary data that generally present low contrast and uneven illumination characteristics.

On Non-simple Marked Point Processes

Annals of the Institute of Statistical Mathematics, 2006
The existence and uniqueness of the compensator for simple point processes has long been known. However, relatively little is known about non-simple point processes. Non-simple point processes are not uniquely determined by their conditional intensity and compensator.

Grouping for random marked point processes

J. Inf. Process. Cybern., 1984
To evaluate the decisions of the hierarchical classifier investigated here, it is necessary to know which classification rates are reachable with random feature values. For answering this question a random marked point process model is used.

Basics of Stochastic Processes, Point and Marked Point Processes

2015
The study of the dynamic performance of engineered systems subject to uncertainty requires the use of tools from stochastic processes. Although stochastic processes have been used extensively in many disciplines (e.g., see [1, 2, 3, 4]), this chapter will focus on the the mathematical background that supports the models presented later in the book. The

On the local odds ratio between points and marks in marked point processes

Spatial Statistics, 2014
Abstract Marked point processes are widely used stochastic models for representing a finite number of natural hazard events located in space and time and their data often associate event measurements (i.e. marks) with event locations (i.e. points). An interesting statistical problem of marked point processes is to measure and estimate the localized ...

Detection of rolling leukocytes by marked point processes

Journal of Electronic Imaging, 2007
The marked point process (MPP) provides a useful and theoretically well-established tool for integrating spatial information into the image analysis process. We consider the problem of detecting rolling leukocytes within intravital microscopy images. A first stage of the detection method reduces the detection to a set of points, each one representing a
