DL_ReadCharacters_Deploy

Module:	DL_OCR

Loads a deep learning model and prepares its execution on a specific target device.

Name	Type	Description
inModelDirectory	ReadCharactersModelDirectory *	A Read Characters model stored in a specific disk directory. If not set, model is chosen on the basis of inPretrainedModelType.
inPretrainedModelType	OcrPretrainedModel	Type of a pretrained model (distributed with Deep Learning Add-on) to deploy. Ignored if inModelDirectory is set.
inTargetDevice	DeviceType *	A device selected for deploying and executing the model. If not set, device depending on version (CPU/GPU) of installed Deep Learning Add-on is selected.
inExecutionHint	OcrDeployHint *	Prepares the model for an execution with provided settings in advance
outModelId	ReadCharactersModelId	Identifier of the deployed model

In most cases, this filter should be placed in the INITIALIZE section.
Executing this filter may take several seconds.
This filter should be connected to DL_ReadCharacters through the ModelId ports.
By default, the model distributed with Deep Learning Add-on will be deployed. If you have a model trained for a specific case, you can set inModelDirectory to it. Please note, that inModelDirectory have to point to existing directory, containing subdirectory named "models", which, in turn, contains file named "model".
If inExecutionHint is set to NIL, first execution of DL_ReadCharacters will likely take much more time than following ones. To avoid this, fill inExecutionHint with expected parameters of following calls to DL_ReadCharacters. A size of an analysed area may be obtained from the diagnostic output of DL_ReadCharacters. If you still experience huge performance hit on some calls to DL_ReadCharacters, add another DL_ReadCharacters_Deploy with inExecutionHint filled with parameters from a problematic call to DL_ReadCharacters.

Passing NIL as inTargetDevice (which is default), is identical to passing DeviceType::CUDA on GPU version of Deep Learning Addon and DeviceType::CPU on CPU version on Deep Learning Addon.
GPU version of Deep Learning Addon supports DeviceType::CUDA and DeviceType::CPU as inTargetDevice value.
CPU version of Deep Learning Addon supports only DeviceType::CPU as inTargetDevice value.

This filter is available on Basic Complexity Level.

This filter is disabled in Lite Edition. It is available only in full, Adaptive Vision Studio Professional version.

This filter is member of DL_Deploy filter group.
