Abstract:
1. A method of distinguishing glyphs from non-glyph image artifacts in an input image, said method comprising: providing a data processing device to implement the following steps: defining a connectedness threshold, said connectedness threshold being a numeric value between a pre-specified numeric range; defining a numeric effort value, said effort value specifying a fixed number of repetitions; assigning foreground pixels of said input image a first connectedness value and assigning non-foreground pixels of said input image a second connectedness value; iterating steps (a) through (d), until the number of iterations matches said effort value, wherein each iteration has a corresponding and predefined scanning pattern and bit mask, said bit mask designating a center pixel location and designating neighboring pixel locations to be considered in the following steps;
