The LTI-Lib is an object oriented library with algorithms and data
structures frequently used in image processing and computer vision.
It has been developed at the Chair of Technical Computer Science
(Lehrstuhl fuer Technische Informatik) LTI at the RWTH-Aachen
University, as part of many research projects in computer vision
dealing with robotics, object recognition and sing language and
gesture recognition.

The main goal of the LTI-Lib is to provide an object oriented
library in C++, which simplifies the code sharing and maintenance, but
still providing fast algorithms that can be used in real applications.

The LTI-Lib is free software; permission to use, copy, modify, and

Following files can be used with the LTI-Lib but are NOT part of it
due to some License issues:

---
Functors based on the SUSAN algorithms.

  A UK pantent has been granted for these algorithms:

  * "Method for digitally processing images to determine the position
  * of edges and/or corners therein for guidance of unmanned vehicle",
  * UK Patent 2272285. Proprietor: Secretary of State for Defence,
  * UK. 15 January 1997

  For this reason the code using them cannot be released under the LGPL
  License.  You can use the files under the original SUSAN-Code
  conditions: 

  * This code is issued for research purposes only and remains the
  * property of the UK Secretary of State for Defence. This code must
  * not be passed on without this header information being kept
  * intact. This code must not be sold.

  The files using SUSAN algorithms in the LTI-Lib are the following:
  
  ltiSusan.h        ltiSusan.cpp
  ltiSusanCorners.h ltiSusanCorners.cpp
  ltiSusanDenoise.h ltiSusanDenoise.cpp
  ltiSusanEdges.h   ltiSusanEdges.cpp

  See the header in this files for more details.

---
Functors for reading and writing png and jpeg files.

  This files are based on the code by John M. Miano (Colosseum
  Builders, Inc.), which are released under their own license.  All
  source files in the io/jpeg and io/png directories are released
  with the original Miano's code coditions, and NOT under LGPL:

  * Permision is granted to use, modify this software provided these conditions
  * are followed:
  *
  * 1. You understand this software comes with no warranties of any kind
  *    whatsoever.
  * 2. You assume full responsibility for the use of this software and transmit
  *    no liability to the authors.
  * 3. You assume the responsility for obtaining licenses for from any patent
  *    holders.
  * 4. If you distribute this code in source form, you must include this file
  *    unmodified and document the changes you have made.
  * 5. If you incorporate this code in a product distributed without
  *    source code you state included in your documentation that it is
  *    based in part on software from Colosseum Builders, Inc.
