Method and apparatus for processing low resolution images of degraded bar code symbols. |
摘要 |
<p>A system is disclosed for processing a two dimensional digital image representative of a bar code symbol. The bar code symbol is oriented in a bar direction. The system includes means for dividing the two dimensional image into a plurality of two dimensional sections perpendicular to the bar direction. Means (1010) for determining information representative of the intensity of a plurality of such sections is also provided. A one dimensional intensity projection signal is formed from the determined information. The system also includes means (1050) for calculating the areas of a plurality of regions described by the projection signal. The widths of a plurality of bars in the bar code symbol are determined from the calculated areas. <IMAGE></p> |
