15. A handwritten object detector that detects a structured handwritten object in a handwritten document, the handwritten object detector comprising: a preprocessor that forms a list of curvilinear segments from a portion of the handwritten document and constructs a set of component objects from the list of curvilinear segments; a feature extractor that obtains a logical structure of a candidate handwritten object from the set of component objects, analyzes content within the candidate table, and determines confidence levels associated with the logical structure and the content; and a classification module that forms a classifier from the confidence levels and that determines whether the candidate table corresponds to a validated handwritten object when the classifier is larger than a predetermined threshold.
