# Introduction to Dynamsoft Capture Vision C++ Edition

Dynamsoft Capture Vision (DCV) C++ Edition enables you to develop highly customizable applications for barcode reading, label recognition, document border detection, and result parsing with C++ language.

Dynamsoft Capture Vision is an aggregating SDK of a series of specific functional products including:

- Dynamsoft Barcode Reader (DBR): enables users to quickly deploy barcode scanning functionality on all common barcodes such as 1D, QR, PDF417, etc.

- Dynamsoft Label Recognizer (DLR): recognizes meaningful zonal text or symbols within an image, commonly referred to as a "Label" in this context.

- Dynamsoft Document Normalizer (DDN): detects quadrilaterals (or "quads") in images, such as document or table boundaries, and then perform document normalization on the images within those detected quads.

- Dynamsoft Code Parser (DCP): extracts meaningful fields from text/bytes into human-readable information, typically used for post-processing results generated by DBR/DLR.
