Advanced Denoising Model for QR Code Images Using Hough Transformation and Convolutional Neural Networks

Abstract

Quick Response (QR) code, a trademark for a two-dimensional code, has gained significant popularity in various sectors due to its innovative automatic identification and data detection capabilities in images. This research aims to enhance QR code identification rates by employing an effective pre-processing and detection method to mitigate noise levels in images with complicated backgrounds or uneven illumination. High-speed transformations on image blocks are utilized to improve recognition in these challenging conditions. A Convolutional Neural Network (CNN), a specialized network architecture for deep learning algorithms, is employed for QR image recognition and other pixel-based processing tasks. CNNs simplify the visuals without sacrificing essential information required for accurate predictions. In this paper, we propose an efficient Noise Removal in Quick Response Code Images using Hough Transformation (NRQRCI-HT) combined with CNN for noise reduction and accurate data identification. This method is benchmarked against traditional techniques, demonstrating superior performance levels in both noise removal and data identification accuracy.
