Image Preprocessing and OCR Accuracy in C#
PSPDFKit GdPicture.NET Library allows you to automatically preprocess and correct poorly scanned documents. Leverage automatic image correction and preprocessing to improve readability (automatic deskew, invert, noise removal, and more). Explore our guides and code samples to learn how you can quickly integrate our image preprocessing technology into your application or workflow.
PSPDFKit SDKs are deployed in some of the world’s most popular applications, such as those made by Autodesk, Disney, DocuSign, Dropbox, IBM, and Lufthansa.
Don’t preprocess documents before recognizing text with OCR. The GdPicture.NET OCR engine preprocesses documents automatically with better results than manual preprocessing.
