    摘要： Flexible and efficient systems and methods for organizing, analyzing, and processing digital ink incrementally analyze input data (e.g., representing ink strokes) as the user continues to add to, edit, or modify the data. In this manner, processing is performed promptly as the ink is entered, and the processing system and method can effectively keep up with the user. This prevents long processing delays, because the systems and methods need not first process a large volume of ink data present after the user has entered has completely filled a page with ink.

    摘要： Annotation recognition and parsing is accomplished by first recognizing and grouping shapes such that relationships between the annotations and the underlying text and/or images can be determined. The recognition and grouping is followed by categorization of recognized annotations according to predefined types. The classification may be according to functionality, relation to content, and the like. In a third phase, the annotations are anchored to the underlying text or images they are found to be related to.

    摘要： Electronic ink layout analysis systems and methods provide flexibility and efficiency in organizing, analyzing, and processing digital ink. These layout analysis systems and methods allow users substantial freedom in entering electronic ink into a pen-based computer system. Using these systems and methods, a user's input digital ink is not constrained by requirements that a user write in a specific screen orientation, that a user write in one specific orientation on all portions of a page, or that a user write using a specific minimum or maximum sized stroke. Rather, the systems and methods freely allow the user to write anywhere on a given page, in any orientation or size, while still enabling effective and efficient handwriting recognition and other processing of the input digital ink.

    摘要： Techniques for efficiently and accurately organizing freeform handwriting into lines. A global cost function is employed to find the simplest partitioning of electronic ink strokes into line groups that also maximize the “goodness” of the resulting lines and the consistency of their configuration. The “goodness” of a line may be based upon its linear regression error and the horizontal and vertical compactness of the strokes making up the line. The line consistency configuration for a grouping of strokes is measured by the angle difference between neighboring groups. The global cost function also takes into account the complexity of the stroke partitioning, measured by the number of lines into which the strokes are grouped. An initial grouping of strokes is made, and the cost for this initial grouping is determined. Alternate groupings of the initial stroke grouping are then generated. The global cost of each of these alternate stroke groupings is then calculated, and the stroke grouping that produces the largest global cost decrease from the global cost of the original grouping is selected. The alternate grouping creation, cost determination and evaluation, and grouping selection process then is repeated until the global cost for new grouping alternates no longer decreases.
