22.2.2 Adjusting the Outlined Areas
The outlined text areas need to be cleansed of waste lines. This happens based on the
knowledge that most lines overlap the outlined text areas, and are connected to other
lines in the same area.
When adjusting the text areas, all pixel traces will be deleted, which will also cut the
borders of the text areas. This process happens automatically during the conversion.
The graphics below can visually explain this procedure:
22.2.3 Recognition of Pattern
22.2.3.1 Correcting Errors at the Pixel Level
The proximity of rough pixels to adjacent pixels can be corrected by deleting single pixels
or adding missing pixels. By doing so, the recall ratio is raised when matching patterns.
It is however highly dependent on the contrast of the le.
