Template
Match
Template Matching is a technique in digital signal processing for finding small parts of a
signal which match a template. The idea of template matching is to create a model of a signal of
interest (the template, or kernel) and then to search over the recorded data for objects that
match the template. To create a template, select a region of interest using the two cursors. Click
Create Template from data between cursors to create a baseline for the template. For each
point in the template, you can set the acceptable tolerance. The tolerance can be fixed for all
points or variable. In case of variable tolerance, you set the high and the low limits of the
tolerance separately. You can move the complete line up/down using Block Move Cursor, or
you can move only certain segments of the curve using freehand Move using. When using the
freehand move, you also have to specify the number of points each move will influence.
Once a template is created, the program will find segments of the data where each datapoint
in the segment matches the template within the tolerance for each point.
