Detection performance of ZXing was assessed on close to 2 million synthetic images for three types of barcodes: QR Code, MaxiCode, and EAN-13 1D barcode. Problematic angles where decoding often fails were found, for example 45, 135, 225 and 315 degrees for QR Codes.Scheuermann, C., Werner, M., Kessel, M., Linnhoff-Popien, C., & Verclas, S. A. W.
