Patent ID: 8681156

Claim:
A method, using an electronic device or computer, for creating a vector representation of portions of an image from a set of input samples representing user physical inputs, the method comprising: receiving, from a digital input device, at least one input sample from the set of input samples; determining an analysis window to be used in the filtering of at least some of the set of input samples, wherein the analysis window contains the at least some of the set of input samples, wherein the analysis window has a leading edge and a trailing edge such that a size of the analysis window is a distance between the leading edge and the trailing edge, and wherein the determining includes at least determining a position for the trailing edge; filtering the at least some of the set of input samples based on the analysis window to generate a modified set of input samples; generating a vector representation based on the modified set of input samples; determining an updated size for the analysis window if the input samples within the window have moved less than a threshold distance during the filtering; and outputting the vector representation.
