Abstract:
1. A method to process digital data, the method comprising: receiving digital data comprising values, the values assigned to regions and representing quantities of a wave form over the regions; selecting a region of the regions, wherein the region is assigned a value of the digital data; dividing the region into a plurality of subregions; and assigning a value to each of the plurality of subregions, wherein the average of the values of the subregions, weighted by measures of the subregions, is approximately equal to the value of the region, thereby increasing the number of data points of the digital data, wherein assigning a value to a subregion comprises assigning a value based upon the value of the region and the value of neighboring regions, wherein: the region comprises an interval; the plurality of subregions comprise a first and a second subinterval of the interval; the neighboring regions comprise a first and a second neighboring region, wherein the first neighboring region neighbors the first subinterval and the second neighboring region neighbors the second subinterval; and assigning a value to each subregion comprises assigning a value to each subregion based upon the value of the region and values of the neighboring regions, and wherein assigning a value to each subregion based upon the value of the region and values of the neighboring regions comprises: selecting a function f piecewise linear over the subregions; and assigning to each subregion an integral of f over the subregion divided by a measure of the subregion, wherein a value of an integral of f over the region divided by a measure of the region is approximately equal to the value of the region.
