Abstract
A bar code reader decodes a bar code symbol in a pixel image by transforming the data corresponding to the symbol along a first scan line, where the transformation comprises rotation and stretching. The reader generates a composite vector and a count vector from the transformed data. The reader then transforms (by rotating and stretching) another set of data corresponding to the symbol along a second scan line. The reader updates the composite and count vectors using the second set of transformed data. The reader then generates a one-dimensional composite signal from the composite and count vectors. The reader decodes the symbol by decoding the composite signal.
