Abstract: Tampering of documents is monotonically growing by posing challenges to forensic scientists. There is a great need to develop alternative solutions for forensic characterization of printers.

Abstract: Irregularly sampling a spatially stationary random field does not yield a graph stationary signal in general. Based on this observation, we build a definition of graph stationarity based on ...

The code supports 2D and 3D ordinary and universal kriging. Standard variogram models (linear, power, spherical, gaussian, exponential) are built in, but custom variogram models can also be used. The ...

Sampling designs and estimation procedures are considered for the spatial variogram when no information on magnitude or scale of variation of a spatial variable is available. Design-based solutions to ...

Processes in space and time. Statistical models and methods for spatially varying phenomena, that is, where the geographical position of measurements matters. Homogeneous/non homogeneous processes.
