The Evernote Corporation patent solves the following problem:
A trajectory of the moving point on the screen, like a pen stroke the electronic ink or a trace of an out-of-EKG, often described by a multi-component signal representing the trajectory parametric form. For example, a pen stroke of simple electronic ink is a simple curve described by a two-phase parametric representation, ie a set of sample points specified as coordinate pairs. Luna curve described by a three-phase parametric representation can be given, in particular, the advanced graphic tablets sensitive to the distance between the pen and the surface of the tablet. A number of additional components, representing physical entities other than spatial coordinates, can be given in addition to parametric representation of a curve. For example, variable-thickness lines drawn through the pressure-sensitive graphics tablets are flat curve described by a three-part sequence of the sample, an additional sample, which represents the pressure , was added to each sample set of coordinates.
Our analysis of this patent is as follows:
Evernote Corporation’s patent US 9223417 B1 deals with Method and apparatus for on-the-run processing of electronic ink using digital filtering and adaptive parameterization.
A method and system for on-the-run processing of source data revealed. In one embodiment, the system includes an input device to track moving objects, like a pen, an on-the-run filter, with the input device, to perform the denoising data sources without noticeable shrinkage following the use recursive filtering reparameterization, and a storage device, coupled with the on-the-run filter, compress and store the data.
