Class ModelType
Specifies the type of ML model to use for advanced OCR operations.
Different model types offer trade-offs between speed and accuracy.

Syntax
public sealed class ModelType : EnumChoosing the machine-learning model behind an advanced read runs through ModelType, the second argument to IronTesseract.ReadDocumentAdvanced. Normal is the standard model, tuned for speed and general documents, and is the right default for most scans. Enhanced trades processing time for higher accuracy on challenging images, complex layouts, or low-quality sources, so reach for it when a Normal read leaves errors. The advanced document read how-to walks through the workflow, and the read table how-to uses the result it produces.
OcrDocAdvancedResult result = ironTesseract.ReadDocumentAdvanced(input, ModelType.Enhanced);Fields
Enhanced
Enhanced recognition model optimized for accuracy.
Provides higher accuracy for challenging images at the cost of increased processing time.
Recommended for documents with complex layouts, low quality images, or when maximum accuracy is required.
