2007 <strong>–</strong> <strong>2008</strong> <strong>Final</strong> <strong>Year</strong> <strong>Project</strong> <strong>–</strong> <strong>1st</strong> <strong>Term</strong> <strong>Report</strong><br />

After computing the all the values, the warping path, which is the shortest path<br />

from the blue square to the red square can then be found, which is shown in the figure<br />

below:<br />

Fig. 3.10 DTW grid with warping path found [11]<br />

With this warping path, a non-linear mapping between 2 curves is formed, and the<br />

error is then computed as well.<br />

Fig. 3.11 A non-linear mapping between 2 different curves [11]<br />

Fig. 3.11 shows a non-linear mapping between curves S and P mentioned<br />

previously. Attention can be drawn to the coloured (and bolded) lines, in which some<br />

points map to multiple points, and some other points are mapped with multiple points.<br />

<strong>The</strong> mapping is based on the result from the grid with warping path found.<br />
