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