Abstract
Systems and methods for reordering unconstrained handwriting data using both spatial and temporal interrelationships prior to recognition, and for spatially organizing and formatting machine recognized transcription results. The present invention allows a machine recognizer to generate and present a full and accurate transcription of unconstrained handwriting in its correct spatial context such that the transcription output can appear to “mirror” the corresponding handwriting.
Claims26
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for spatially formatting recognition results of handwriting data, wherein the handwriting data comprises a set of strokes, each stroke comprising a set of x-y coordinates, the method steps comprising:
- determining bounding region information for unconstrained handwriting data based on x-y coordinates associated with the unconstrained handwriting data;
- generating recognition results for the unconstrained handwriting data, the recognition results comprising recognized text corresponding to the unconstrained handwriting data;
- and
- spatially formatting the recognition results, wherein the step of spatially formatting the recognition results comprises positioning the recognized text on a display page in substantially a same proximate spatial location as the corresponding unconstrained handwriting data is located on an ink page using the bounding region information for the corresponding unconstrained handwriting data.
A system for spatially formatting recognition results of handwriting data, wherein the handwriting data comprises a set of strokes, each stroke comprising a set of x-y coordinates, the system comprising:
- means for determining bounding region information for unconstrained handwriting data based on x-y coordinates associated with the unconstrained handwriting data;
- means for generating recognition results for the unconstrained handwriting data, the recognition results comprising recognized text corresponding to the unconstrained handwriting data;
- and
- means for spatially formatting the recognition results, wherein the means for spatially formatting the recognition results comprises means for positioning the recognized text on a display page in substantially a same proximate spatial location as the corresponding unconstrained handwriting data is located on an ink page using the bounding region information for the corresponding unconstrained handwriting data.
