read_texture_inspection_model — Read a texture inspection model from a file.
read_texture_inspection_model reads a texture inspection model that has been stored with write_texture_inspection_model. Since the training of a texture inspection model can consume a relatively long time, the texture inspection model is typically trained in an offline process and written to a file with write_texture_inspection_model. In the online process the texture inspection model is read with read_texture_inspection_model and subsequently used for evaluation with apply_texture_inspection_model. The default HALCON file extension for the texture inspection model is 'htim'.
After reading a trained texture inspection model, it is possible to classify test images using apply_texture_inspection_model. However, retraining this model can only be done, if the read model has images. Furthermore, modifying parameters of the model leads to an entire retraining.
For an explanation of the concept of the texture inspection see the introduction of chapter Inspection / Texture Inspection.
This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.
File extension: .htim

If the parameters are valid, the operator read_texture_inspection_model returns the value 2 (H_MSG_TRUE). If necessary an exception is raised.
