Described is a system and method for bar code detection. The method comprises generating a digitized bar pattern (DBP) including a series of elements corresponding to elements of a scanned bar code, and identifying a first set of margins around a first portion of the series of elements. When an attempt to decode the first portion is unsuccessful, the first portion is analyzed to determine a second set of margins around a second portion of the series of elements, the second set of margins being within the first set of margins, and the second portion is input to a decoding algorithm.
