Abstract
The present invention relates to a method of down-sampling data values. A first set of data values comprise a central data value and peripheral values of original data spatially surrounding the central data value. The central and peripheral values are compared to determine whether any differences exceed a threshold. Whenever a difference does exceed a threshold, a clipped value based upon the central data value replaces the corresponding peripheral value, thereby producing a second set of data values.
