Application ID: 12332913

Base Claim:
1. A method of detecting dominant points on text characters in a scanned document, comprising: executing an optical character recognition (OCR) algorithm that recognizes a text character in the scanned document; performing a table lookup that identifies one or more dominant point detection rules for detecting the dominant points; applying the one or more identified dominant point detection rules to the text character to detect dominant points on the text character; fitting one or more curves to each text character outline between neighboring dominant points to convert the text character from a bitmap to a vector representation using the detected dominant points; and storing the vectorized text character to memory for use in a vector representation of the scanned document.

Claim 5:
5. The method of claim 1 , wherein each dominant point is calculated as: 
 arg Max (x,y) x cost+ y sint  (1) where the dominant point is searched for on all boundary points (x,y) of the text character, t is a parameter in the one or more identified vectorization rules that determines the projection direction of the search for the dominant point.
