    Mini QR

    Mini QR

    Create & scan cute qr codes easily

    Mini QR is a web app focused on making QR codes feel friendly and design-forward, combining a polished QR generator with a built-in scanner so you can both create and decode codes in the same place. It emphasizes customization so the QR you generate can match a brand, event theme, or personal style, including color and styling controls, framed layouts with labels, and the ability to add a logo image. Because QR reliability matters as much as looks, it exposes practical settings like error correction levels so you can balance data density with scannability, especially when adding a logo or encoding larger payloads. The scanning side supports camera-based scanning and image uploads, and it recognizes common QR content types such as URLs, emails, phone numbers, SMS messages, Wi-Fi credentials, and other structured payloads so the next action is obvious. It also supports workflows for producing many codes at once by importing CSV data and exporting batches.

    FastQR

    FastQR

    A Fast QR code detector for arbitrarily acquired images

    Applications of Quick Response (QR) codes enable rich context interaction through creation of links between physical objects and internet resources. In spite of the widespread use of this kind of barcode, applications for visually impaired people and robots are not common because existing decoders assume that the symbol is properly framed during image acquisition. This project implements a two-stage component-based approach to perform accurate detection of QR code symbols in arbitrarily acquired images. In the first stage a cascade classifier to detect parts of the symbol is trained using the rapid object detection framework proposed by Viola-Jones. In the second stage, detected patterns are aggregated in order to evaluate if they are spatially arranged in a way that is geometrically consistent with the components of a QR code symbol. OpenCV 2.2+ is required.

    QPyDesk

    QPyDesk

    Code editor and real-time QR code generator for QPython

    QPyDesk is a code editor, and real-time QR code generator for QPython. It is a Python code editor with syntax highlighting that also generates the QR code that represents said code in real time. This application also allows you to print the generated QR code to distribute the created application. However, because QR codes have a limited storage capacity, if the code is very long, QPyDesk creates a QR code that is only valid while the application is running, that is, the QR code generated in this case is useless for distribute the application, but it is still useful to check the operation of the script while it is encoded from the computer. When these circumstances occur, QPyDesk notifies the user and disables the print button. QPyDesk gives dynamism during the development of applications for QPython / Android, since it takes advantage of the QPython QR code reader to work comfortably from the computer for the android device.

    SlowQR

    SlowQR

    QR code reader/scanner/generator

    SlowQR allows to scan QR codes from images. Some manual interaction for distorted codes is possible. Due to missing hardware-accelerated drawing support, automatic recognition may be slow, hence the name. New features: - creation/editing of QR codes. - support of images with perspective - optional experimental offscreen hardware acceleration (via openGL 2-FBOs)
