The goal of the DTREND project is to create a research tool which implements the Dynamic Time Warping algorithm. The tool will be used in research projects of VTT Electronics. These research projects are concerned with process monitoring and diagnostics. The main goal of the DTREND tool is recognition of patterns in measurement time series.
The most important characteristic of the DTW algorithm and DTREND tool is the ability to cope with variation on the time axis, i.e. some parts of the signal may be shrunken whereas other parts may be stretched.
The DTREND tool must be divided into two parts: A function library, which implements the DTW algorithm and a executable which utilizes the function library. The executable part is called the GUI part in this document, even though strictly speaking, not all of its functions are those of a GUI. The parts of the software are visualized in Figure 1.
