ABSTRACT:
A method and apparatus for decoding profiles which fail to resolve narrow elements in complex multi-width symbols, first begins by identifying which elements in the profile are resolved. Second, the environments surrounding each resolved element are examined. Third, several closure boundaries are determined, and the widths of resolved elements are determined at a selected threshold. The size of each resolved element is determined based on its measured width at a threshold selected based on the environment surrounding the resolved element. Fourth, the distances between the centers of the resolved elements are determined. Thereafter, an X-dimension is determined for 1-wide narrow elements unresolved in the profile. Based on the X-dimension and known center distances, a matrix is constructed for determining the number of narrow elements unresolved between two resolved elements. Based on the measured center distances, the resolved element widths and the matrix, all of the elements are identified in the profile and the profile is subsequently decoded.
