摘要： The invention relates to a method implemented by a computing device (100) for processing math and text in handwriting, comprising: identifying symbols by performing handwriting recognition on a plurality of strokes (SK); classifying, as a first classification, first symbols as either a text symbol candidate or a math symbol candidate with a confidence score reaching a first threshold; classifying, as a second classification, second symbols other than first symbols as either a text symbol candidate or a math symbol candidate with a respective confidence score by applying predefined spatial syntactic rules (RL2); updating or confirming, as a third classification, a result of the second classification by establishing semantic connections between symbols and comparing the semantic connections with the result of the second classification; and recognising each symbol as either text or math based on a result of said third classification.

摘要： A method for recognizing gesture strokes in user input applied onto an electronic document, comprising: receiving data based on the user input, the data representing a stroke and comprising a plurality of ink points and a plurality of timestamps associated with the plurality of ink points; segmenting the plurality of ink points into a plurality of segments each corresponding to a respective sub-stroke and comprising a respective subset of the plurality of ink points; determining a scale of the electronic document; generating a plurality of feature vectors based on the plurality of segments; normalizing a subset of the feature vectors according to the scale; and applying the plurality of feature vectors to a trained stroke classifier to generate a vector of probabilities including a probability that the stroke is a non-gesture stroke and a probability that the stroke is a given gesture stroke of a set of gesture types.
