General pattern recognition in images using WND-CHARM.
Please see our new WND-CHARM Google Code website to download the latest releases, and to access our source code repository, issue tracker, and documentation.
Description --
-
The wndchrm command-line utility takes a root directory path as a parameter and computes up to 2600 image features for each image in the subdirectories that define the image classes.
The utility then splits the images into training and test sets, classifies them, and produces html reports.
The code was tested on MacOS X and Linux.
Use "./configure", "make", "sudo make install" after untaring the archive. Then type "wndchrm -h" for instructions.

Dependencies: Wndchrm requires the installation of two open-source libraries - LibTIFF and FFTW. The libraries can downloaded from:
-
MS Windows Binaries

System Requirements --
-
Recommended Hardware: 2 GB RAM, 10 GB HD space, 2 GHZ CPU.
Please be aware that this utility is very computationally intensive. Multiple instances of wndchrm can work concurrently on the same dataset on multi-core/multi-processor CPUs.
Simply use the same command line to launch as many instances of wndchrm as there are CPU cores available.
-
Software: GCC compiler must be installed, LibTIFF and FFTW.
-
Wndchrm was tested using Linux (Fedora Core, Red Hat) and MacOS X, but should also run with other Unix and Linux distributions.
Installation difficulties are expected if Libtool is compiled with a different compiler version than the one used for compiling LibTIFF (this situation is more likely with upgraded operating systems).
This problem can be solved by installing a newer gcc version.
