Mathematical Modeling of Distributed Image Processing Algorithms

Abstract

Abstract-Satellite images play an important role in developing Geographical Information System software applications that prove to be useful for different Earth Science phenomena analysis. Accurate results are obtained from high resolution images, or by applying the same algorithm multiple times over a specific input data set. In both cases the data volume that needs to be processed is large, and usually involves distributed infrastructures. In order for non-technical users to use these algorithms, they should be described in a flexible manner, using workflow structure models. This paper highlights the main achievements within the GreenLand platform, regarding scheduling, executing, and monitoring the Grid processes. Its development is based on simple, but powerful, notion of mathematical directed acyclic graphs that are used in parallel and distributed executions over the Grid infrastructure.

“…A good example is the process brokering approach developed by the Institute for Atmospheric Pollution Research, National Research Council of Italy (Bigagli, Santoro, Mazzetti, & Nativi, ). More specifically, a business process broker (BPB) is a distributed information system for creating, validating, editing, storing, publishing, and executing geospatial‐modeling workflows (Bigagli et al, ; Colceriu et al, ). A BPB is a component that takes a formal description of a scientific business process, and translates it in an executable process which can be run on multiple and remote processing and workflow services.…”
