LSD-MEX: Line Segment Detector for matlab

Download

svn co https://iie.fing.edu.uy/avn/matlab/matlab/bones/lsd-1.5-mex/

Instructions

see the readme_matlab.txt

Parameters: Command line parameter handling

Small set of classes to handle command line arguments and configuration files in a very simple and flexible way.

Features

• Tested in windows, linux and mac.
• Demo provided
• multiplatform compilation via cmake.
• default values for the parameters
• example configuration files are created
• arguments can be read from files, command line or both
• Logging facilities with different log levels.

Download

svn co https://iie.fing.edu.uy/avn/codigo/parameters

Compilation

<bash> cmake . make </bash>

Examples

• demo.cpp
• run it:
  • ./demo -h: shows help
  • ./demo -create=conf.cfg: creates a new configuration file with default values
  • ./demo -config=conf.cfg: reads options from the conf.cfg configuration file
  • ./demo -num_eyes=3: sets the value of an option directly in the command line

Usage

You can use it like this: ./demo -config=myconf.cfg and in the myconf.cfg file you will find "name=value" pairs. For instance input_image=lena.png Conversely, you could run it like this ./demo -input_image=lena.png without the configuration file.

    • last updated: 2006.12.05
    • contributed: Gabriele Facciolo
    • tested: on Megawave 2, but the main program is written in plain C without Megawave structures.
