QR Code Scanning and Decoding in MATLAB

This is a self-developed test program for QR code scanning implemented in MATLAB. The program provides fundamental capabilities including scanning and decoding QR codes. QR code scanning involves capturing images through a camera and subsequently decoding these images to extract embedded information. The decoding process converts captured QR code images into readable text or links. This MATLAB-based solution utilizes built-in functions and custom algorithms to achieve efficient image processing. Key implementation aspects include: - Image acquisition via MATLAB's image acquisition toolbox or image file input - Preprocessing techniques (e.g., grayscale conversion, noise reduction) using imread() and imgaussfilt() functions - QR code detection through pattern recognition algorithms and boundary detection - Data decoding employing error correction algorithms and matrix transformation methods The program enables fast and accurate QR code scanning, converting codes into meaningful information such as text, URLs, or other data types. It offers users a convenient method to access hidden content within QR codes. Additional features include processing scanned results and displaying decoded content through MATLAB's plotting and text display functions. Overall, this test program provides MATLAB users with a straightforward yet effective approach to implement QR code scanning and decoding functionality, demonstrating practical computer vision applications within the MATLAB environment.
