Aesthetic QR code generation with background contrast enhancement and user interaction

Abstract

Quick Response Code, abbreviated as QR code, is a two dimensional matrix which is extensively used both in the automotive industry and the general commercial applications currently. Compared with traditional barcodes, QR code is prevalent for its enormous information capacity and efficient error correction mechanism. Moreover, the standard QR codes possess a high decode rate at the expense of the aesthetic appearance. With an intension to resolve the contradiction, we propose a novel aesthetic QR code generation method. Differing from previous works, which mainly rely on the error correction mechanism, we first enhance the contrast of the background image so that more modules can be eliminated after initial threshold based module elimination, while maintaining the readability and demonstrate visual information to customers simultaneously. User interaction can be further adopted to delete modules as customer required using error correction mechanism.
