Systems and methods for detecting and decoding 4-state barcodes with extreme bar dilation are disclosed. The method is implemented in a computing device and includes: separating an extracted image of a barcode into a top half and a bottom half; estimating bar positions and then sampling heights of the top and bottom images at each position; using adjacent bar height differences to determine the top and bottom of the tracker portion for each bar position; removing the tracker contribution to the top and bottom heights at each bar position; sending the resulting sequence of bars with ascender and descender information to a decoder for decoding processes.
