The Barcode Detection API is a subset of the Shape Detection API which provides the ability to detect and decode barcodes in an image provided by script. The image may come from any type of image buffer source such as an <image>, <video> or <canvas> tag. Some native platforms include built-in libraries for performing text detection and optical character recognition (OCR) in images. The availability of these libraries means that developers do not need to include a large third party library.

Comments

This feature depends on built-in face detection support which is only provided by Android* and macOS** at the moment. * Requires a device with the Play support libraries installed. ** Detection performance is improved in 10.13 through use of hardware acceleration in the Vision Framework.
