摘要：
The present invention discloses a system and a method for decoding QR codes in complex scenes, a system and a method for generating multi-layer color QR codes and applications enabled by the systems and methods. The method for decoding a QR code may include detecting rough locations of the QR code by a learning-based QR code detector which is pre-trained off-line; localizing finder patterns and alignment patterns within each detected location; correcting geometric distortion of each QR code, based on the localized finder patterns and alignment patterns; restoring a color of each data module within each corrected QR code by a learning-based classifier; and decoding the QR code from each restored QR code. The application also discloses a system and a method to determine the optimal setting parameters for creating a multi-layer QR code to fulfill the user's requirements. Some applications enabled by these systems and methods are also disclosed.
