Motion template is a technique in image processing for finding a small part of an image or silhouette that matches a template image. This template matcher is used to make comparisons with respect to similarity and to examine the likeness or difference. Templates might potentially require sampling of a large number of points. However, it is possible to reduce these numbers of points by reducing the resolution of the search; another technique to improve these templates is to use pyramid images.
In OpenCV's examples ([opencv_source_code]/samples/c/motempl.c), a related program can be found.
We now assume that we have a good silhouette or template. New silhouettes are then captured and overlaid using the current time stamp as the weight. These sequentially fading silhouettes record the history of the previous movement and are thus referred to as the Motion history template. Silhouettes whose time stamp is more than a specified DURATION older than...
