3. Executables UsageΒΆ

This project generates the following command line executables:

  • fmdt-detect,

  • fmdt-visu,

  • fmdt-check,

  • fmdt-maxred.

fmdt-detect is an optimized and efficient C/C++ code for meteors detection. It produces only text outputs. The main results are the detected tracks and they can be read on the standard output (in the terminal). If the CMake -DFMDT_AFF3CT_RUNTIME=ON option is used to compile the project, then additional detection binaries are produced:

  • fmdt-detect-rt-seq: this version comes with new performance measurement tools. However, this is a sequential version and the efficiency should be similar with the standard fmdt-detect executable,

  • fmdt-detect-rt-pip: this version is multi-threaded. Thus, the throughput in term of FPS is much higher than the standard fmdt-detect executable (depending on the CPU target).

Both fmdt-detect-rt-seq and fmdt-detect-rt-pip have the same level of features than the standard fmdt-detect executable.

fmdt-visu mainly uses the fmdt-detect text outputs to generate highlighted video sequences. It can be combined with ground truth to distinguish good detected tracks (true positive) and bad detected tracks (false positive).

fmdt-check compares detected tracks (fmdt-detect) with a given ground truth. The results are shown on the standard output.

fmdt-maxred performs a max-reduction from a video sequence into an image. The produced image is in grayscale mode.

The next sections describe the command line parameters of these tools.
