- Abstract
- The aim of this work is to develop a prototype system, that is a software
tool that contributes to monitor the coastline. In fact it, constituted by a
set of techniques and methods for SAR (Synthetic Aperture Radar) image
segmentation, can aid to investigate the state of conservation of the coastal
environment. The proposed system, called ISC (Interactive System for
Coastline detection) and written in JAVA language, is composed by a
set of Java classes structured in packages and it is based on the level
set method applied to SAR images. In this method, an initial curve
defined on the image evolves according to a PDE (Partial Differential
Equation) model by means of a velocity whose mathematical expression
is related to the characteristics of the image to be segmented. This curve
is deformed until it assumes a stable position at the boundary of the area
to be extracted from the image. We used images SAR PRI (Precision
Image Resolution) acquired during the ERS2 (European Remote Sensing
Satellite) mission. (literal)
