dmt

Computes the max-tree of an image - a hierarchical representation of that image that is the basis for a large family of morphological filters. It is often used as the basis of feature engineering in remote sensing applications.

dmt is written in C++ and may be used as a command line tool. Data is passed to and generaed by the tool in form of HDF5 files.

Dependencies

dmt requires the following dependencies. Please make sure, that these are installed, before attempting to compile the code.

• CMake 3.10+
• C++11 compliant compiler (e.g. g++ 4.9+)
• OpenMP 4.0+ (e.g. g++ 4.9+)
• HDF5 1.8+
• Message Passing Interface (MPI) 2.0+

Compilation

dmt follows the standard CMake project conventions. Create a build directory, change to it, generate the build script and compile it. A convenience short-hand can be found below.

mkdir build && cd build && cmake .. && make

The provided CMake script checks, but does not install, all of the necessary dependencies listed above.

Usage

dmt's command line usage flags are shown below. You may obtain the same message by invoking dmt -h:

dmt - distributed max-tree
Usage: ./dmt <IN_FILE> <IN_DATASET> <OUT_FILE> <OUT_DATASET>

The typical basic usage of dmt is shown below. The line shows a typical high-performance computing setup with multiple distributed nodes and processing cores per node, but also runs on your work stations or laptop. The data is passed to the application in form of an HDF5 file.

mpirun -np <NODES> ./dmt -t <THREADS> <PATH_TO_HDF5_FILE>
