Fixing Low Quality Scans & Images

The IronTesseract OCR Class provides granular control to C# and .NET developers to add OCR (image and PDF to text) functionality to their applications, and also to fine-tune performance to their specific use cases.

By setting variables, a perfect balance between speed and accuracy can be achieved through working with real-world examples. Settings include filter methods on OcrInput such as Deskew, DeNoise, Despeckle, EnhanceResolution, Sharpen, Erode, Dilate, Scale, and Binarize, along with IronTesseract.Language and IronTesseract.Configuration.
