Web1.5.7.1 Subsampling. Subsampling ( Fig. 1.36) is a method that reduces data size by selecting a subset of the original data. The subset is specified by choosing a parameter n, specifying that every n th data point is to be extracted. For example, in structured datasets such as image data and structured grids, selecting every n th point produces ...
