Class OcrResult.Choice
Inheritance
Namespace: IronOcr
Assembly: IronOcr.dll
Syntax
public class Choice : ObjectOcrResult.Choice is one alternative reading the engine considered for a character, paired with how likely it judged that reading to be. It is what you inspect when the top result for a glyph looks wrong and you want to see the runner-up candidates instead of accepting a single guess, which is useful for correction passes and for flagging low-confidence text.
You receive choices from the Choices array on an OcrResult.Character, reached by walking an OcrResult returned from IronTesseract.Read. Each choice exposes just two members: Text, the candidate string for that reading, and Confidence, its statistical confidence as a percentage. The array is ordered so the engine's preferred reading comes first, with weaker alternatives following.
To use it, read a character's Choices, then compare the Confidence values to decide whether the primary reading is trustworthy or whether an alternative is worth substituting. Choices are most informative on noisy or low-quality input where the engine is genuinely uncertain.
The working with OCR results how-to covers reading per-character detail, and the result confidence how-to explains using confidence values.
