|latest version v1.9|
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 Aachen University of Technology, 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.
Many classes encapsulate Windows/Linux functionality in order to simplify dealing with system or hardware specific code (for example classes for multi-threading and synchronization, time measurement and serial port access).The rest of the more than 500 classes deal mainly with one of following fields:
Matrices, Vectors, Tensors, and functors to extract eigenvalues, eigenvectors, linear equations solutions, statistics, etc. are provided.
Classification and Clustering
Radial Basis Function classifiers, Support Vector Machines, k-Means, Fuzzy C-Means, classification statistics are just some examples of what you can do with the LTI-Lib.
The most classes deal with image processing problems. Different segmentation approaches, linear filters, wavelets, steerable filters, und much more are already available.
Visualization and Drawing Tools
The most difficult part when developing image processing algorithms in C++ is showing temporary images while debugging. Due to the object oriented architecture of the LTI-Lib, you just need to create a viewer object and give it the image you need to show. That's it. An if you additionally need to draw some extra information on that image (some text, ellipses, boxes, lines or points) you can use one of the drawing objects. This will help you to save lots of time!
There is also a Wiki for users and developers of the LTI-Lib.
For Windows NT you will need at least the MS Visual C++ 6.0 with Service Pack 5.0 or the MS Visual C++ .NET 2003 (Version .NET 2002 is NOT supported).
For Linux you will require at least GCC 2.95.3.
For both platforms you will need PERL, and if you want to use the viewers (and we think you will!), you will also need to have installed the GTK libraries. See also the on-line documentation for more information.

Projects using the LTI-Lib
For users who work with the LTI-Lib on Windows platforms might like to take a look at Impresario. This is a small Rapid Prototyping System which supports the development and evaluation of simple image processing systems and incorporates the LTI-Lib into an extendable graphical user interface.
More projects which utilize the LTI-Lib are listed separately.
