摘要: Embodiments of the invention relate to decoding encoded barcode information from a camera-captured image by generating binarized sequence and sequence. The is transformed into preprocessed grayscale image, reducing noise enhancing contrast between bars spaces in image. A orientation identified that parallel projected generated projecting pixels along orientation. applying threshold detected peaks valleys barcode-encoding generated, sequence, which each bar module space represented single respective bit extracted
