Abstract
Systems and methods are described that facilitate dominant point detection for text in a scanned document. The dominant points are classified as 'major' (e.g., structural) and 'minor' (e.g., serif). A set of rules or parameters for each character is determined off-line. During the text vectorization, OCR is performed and the rules (parameters) associated with the recognized character are selected. Both major and minor dominant points are detected as a maximization process with the parameter set. For minor dominant points, additional processes are optionally employed.
