General software features

libcrm is an image processing toolkit.

Langage

  • C++
  • using shared pointers (garbage collector)
  • strict object oriented paradigm
  • data saved in XML files

Image processing

Generic processings

  • Matricial convolution
  • Morphology
  • Differential computation (PDE)
  • Colour formats (RGB, L*a*b*, HSV…)
  • etc.

Document images

  • Segmentation
  • Binarisation
  • Pattern recognition
  • etc.

Mathematics

  • Classification and clustering
  • Hidden Markov models
  • Numerical computation
  • Matricial computation
  • Descriptive statistics

GUI

  • libcrn is packaged with a Gtk+ widget library allowing easy creation of graphical user interfaces.
  • A demo is also provided. It allows to quickly test many features of the library.
Context in which the software is used

libcrn is used to create document image processing algorithms.

The library is used in sheer research contexts as well as to create complete software with a GUI (e.g.: image mode search engine, OCR, etc.).
