In their own words
Dynamsoft Label Recognizer
Dynamsoft Label Recognizer is an OCR SDK for extracting alphanumeric characters and standard symbols from images, including codes and other text that does not follow natural-language patterns. Developers can set recognition zones relative to a reference, such as a barcode, and use regular expressions or character models to constrain or check output. A product-label workflow can detect and crop a label, scan barcodes, read text fields, and return structured data in one pass. Supported image formats include BMP, TIFF, JPEG, PNG, and PDF; video recognition can combine partial text results across adjacent frames. Built-in processing can improve contrast, reduce noise, and correct distortion. It can be licensed independently or combined with other Capture Vision modules. Supported environments include Windows, Linux, macOS, Android, iOS, and browser-based JavaScript through WebAssembly, with bindings for JavaScript, Python, C++, C#, .NET, Java, Swift, and Kotlin. The maker describes on-device, on-premise, offline, and air-gapped deployment. A free 30-day SDK trial is offered; pricing starts at $1,249/yr, and there is no free plan.
