===================================================== Surrey Space Centre ridge classification algorithms ===================================================== Copyright (C) 2010-2012 Peter Brett <email@example.com> Introduction ============ This package provides some algorithms for classification of curvilinear features extracted from SAR images of urban areas, as part of research into detection of earthquake damage in urban areas. It was developed at Surrey Space Centre at the University of Surrey in Guildford, UK. For more information, please see: P.T.B. Brett and R. Guida. "Bright line detection in COSMO-SkyMed SAR images of urban areas." In Joint Urban Remote Sensing Event 2011 (JURSE 2011), pages 253-256, 11-13 April 2011. <http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=5764767&tag=1> P.T.B. Brett and R. Guida. "Geometry-based SAR curvilinear feature selection for damage detection. In 9th European Conference on Synthetic Aperture Radar - Invited Papers (EUSAR 2012 - Invited Papers), pages 62-65, 23-26 April 2011. <http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=6216946&tag=1> Programs ======== Two programs are provided: - The 'ridge-classbayes' tool uses a naive Bayesian classifier with two feature variables: return strength and a saliency measure based on ridge strength. - The 'ridge-classarea' tool classifies features using prior probability distributions derived from an idealized urban building model. Installation ============ The 'ssc-ridge-classifiers' package requires the 'mmap()' system call to support the 'MAP_SHARED' and 'MAP_ANONYMOUS' flags. Most recent versions of Linux provide this. Dependencies ------------ In order to compile and install the 'ssc-ridge-classifiers' package, you must have the following tools and libraries installed: - A C compiler and standard library (GCC/glibc are recommended). - The `pkg-config' tool for managing shared libraries. <http://pkgconfig.freedesktop.org/> - The 'ssc-ridge-tools' package. <https://github.com/peter-b/ssc-ridge-tools> - GTK+ (the Gimp Toolkit), version 2.10.0 or later. <http://www.gtk.org/> - GSL (the GNU Scientific Library), version 1.13 or later. <http://wwww.gnu.org/s/gsl/> - LibTIFF. <http://www.libtiff.org/> If you are compiling from the 'ssc-ridge-classifiers' git repository, you will also require: - The `git' version control tool, version 1.6 or newer. <http://git-scm.com/> - GNU Automake, version 1.11.0 or newer. <http://www.gnu.org/software/automake/> - GNU Autoconf, version 2.60 or newer. <http://www.gnu.org/software/autoconf/> - GNU Libtool. <http://www.gnu.org/software/libtool/> Configuration and compilation ----------------------------- If you are building from git, clone the repository and set up the source tree: git clone git://github.com/peter-b/ssc-ridge-classifiers.git cd ssc-ridge-tools ./autogen.sh Otherwise, extract the source files. You can then proceed to configure, compile and install the tools in the usual manner: ./configure make make install For a full list of the options that can be passed to 'configure', please see: ./configure --help License ======= Surrey Space Centre ridge classification algorithms (this package) is freely distributable under the GNU Public License (GPL) version 3.0 or (at your option) any later version.
