html5-qrcode is a client-side JavaScript library that enables QR code and barcode scanning directly in a web browser, processing live video from a device camera or decoding codes from uploaded image files without any server-side involvement. The library handles real-time scanning from continuous camera feeds with adjustable frame rates and scanning regions, while also supporting file-based decoding for static images. The scanner offers configurable behavior through runtime settings, allowing developers to adjust scanning speed, viewfinder region, aspect ratio, and restrict decoding to specifi
GoCV is a computer vision library and Go language binding for OpenCV. It serves as an image processing toolkit and deep learning inference engine, providing programmatic access to a wide range of algorithms for image manipulation, object detection, and video analysis. The project differentiates itself through high-performance native bindings and hardware acceleration. It utilizes a foreign function interface to map Go calls to C++ functions and includes a hardware-agnostic backend dispatch to route neural network tasks to computation engines such as CUDA and OpenVINO. The library covers a br
This project is a multi-format barcode library designed to encode and decode one-dimensional and two-dimensional barcodes across multiple programming languages. It functions as a cross-platform image processor that analyzes visual data to detect, locate, and extract information from patterns in diverse environments, while also providing a standard for mapping structured data into machine-readable formats. The library distinguishes itself through advanced image processing techniques that ensure reliability in real-world conditions. It employs pattern-matching detectors to identify geometric fi
jsqrcode is a JavaScript library for decoding QR codes within a web browser. It functions as a QR code scanner and decoder capable of extracting encoded text and data from various visual sources. The library supports data extraction from static images via URLs and data URLs, as well as from canvas elements. It also provides real-time scanning capabilities by processing live video streams from a device camera through the media devices API. Its internal processing covers pattern detection, pixel sampling, and binary-matrix decoding. It utilizes Reed-Solomon error correction to recover missing
jsQR is a JavaScript library for locating and decoding QR codes directly within a browser or Node.js environment. It functions as a client-side scanner and decoder that extracts text and data from images using pixel arrays, removing the need for server-side processing.
The main features of cozmo/jsqr are: QR Codes, Pattern Recognition, Localization, Geometric Pattern Localization, Image Processing, Perspective Warping, Error Correction Codes, Client-Side Media Processing.
