Class TextRecognitionModel
- Namespace
- OpenCvSharp.Dnn
- Assembly
- OpenCvSharp.dll
This class represents high-level API for text recognition networks. TextRecognitionModel allows to set params for preprocessing input image. TextRecognitionModel creates net from file with trained weights and config, sets preprocessing input, runs forward pass and return recognition result. For TextRecognitionModel, CRNN-CTC is supported.

Constructors
- TextRecognitionModel(Net)
Create model from deep learning network.
- TextRecognitionModel(string, string?)
Create text recognition model from network represented in one of the supported formats. An order of @p model and @p config arguments does not matter.
