A way to introduce the concept of QR images, it is an automatic method to embed the QR codes into color images. This technique can be applied to any color images. The QR information bits are put into the codes over the luminance values. To make it unpleasant the visual perversion of the QR image, the algorithm uses halftoning mask for selection of modified pixels and nonlinear programming techniques to locally optimize luminance levels. A docile model for the probability of error is developed and human visual system model are considered in the quality metric used to minimize the luminance value of the QR image. To minimize the processing time optimization technique is used to consider the common binarization method. It is acceptable for parallel implementations. Results of this project experiment shows graceful disgrace of decoding rate. A visual comparison between the existing and proposed system is shown.
