Better Qr Codes

A custom Python pipeline that embeds full-color images into QR codes while maintaining scannability with standard phone cameras. The technique works by deconstructing a generated QR code into its cellular data. While preserving the critical landing markers, the pipeline reconstructs the data-carrying portions of the code as an image. It overlays this image with a pattern of fine dots, calibrated to manipulate the average luminance within each cell. This ensures that when a scanner samples the cells, it correctly reads them as light or dark, preserving the original data while making the embedded image visible to the human eye.
