More Information
Summary:Flexible and efficient systems and methods for analyzing digital or electronic ink may automatically classify electronic ink strokes on a page into one or more types of stroke (such as drawing strokes, text strokes, music strokes, mathematical strokes, charts, flowcharts, tables, graphs, etc.). The systems and methods may include an input for receiving input ink data including at least one stroke set, and a processor for determining the type of stroke contained in the stroke set based, at least in part, on information regarding the contextual environment relating to the stroke set. The contextual environment relating to the stroke set may include one or more contextual features regarding the stroke set. These contextual features may include, for example, various features relating to the stroke(s) within the first stroke set, features relating to stroke(s) located within a predetermined range of the first stroke set, and/or features relating to stroke(s) associated in some manner with the first stroke set.
