These properties sometimes are crucial to the dynamics and evolutions of ecosystems. This paper started from the fundamental aspects of CA and focused on the development and application of the approach to ecological and ecohydraulics modelling. Application cases include modelling of prey–predator dynamics by stochastic CA and simulation of riparian vegetation successions in a regulated river by rule-based CA. The results indicated that spatially explicit paradigms such as cellular automata (CA) have a strong capability to bridge the local processes and global patterns.

Comparison of spatial patterns between cellular automata model simulations and remote sensing observations
Cellular automata (CA) have been increasingly applied to ecohydraulics modelling owing to its advantages in simulating local behaviours and spatial patterns. However, methods for evaluating CA model performance, mostly comparing with RS observations, have yet to be established. A conventional way is to compute the overall error between model outputs and observations. This aggregated approach wi...
متن کاملEdge Detection Based On Nearest Neighbor Linear Cellular Automata Rules and Fuzzy Rule Based System
Edge Detection is an important task for sharpening the boundary of images to detect the region of interest. This paper applies a linear cellular automata rules and a Mamdani Fuzzy inference model for edge detection in both monochromatic and the RGB images. In the uniform cellular automata a transition matrix has been developed for edge detection. The Results have been compared to the ...
متن کاملEvent-based modelling of ecological systems with asynchronous cellular automata
In this article, we give an example for the modelling of ecological systems with cellular automata based on the description of cell's behaviour by Petri nets. Petri nets ooer a formal modelling technique with event{based, concurrent, asynchronous state changes where graphical symbols are used for the description of states resp. state changes. This allows the formal description of cellular autom...
