F_VN_ExecuteNeuralNetwork

Execute a neural network using the provided image as input and provide the output of one output layer. The function doesn't perform any pre-processing or transformation.
Can use available TwinCAT Job Tasks for executing parallel code regions.

Syntax

Definition:

FUNCTION F_VN_ExecuteNeuralNetwork : HRESULT
VAR_INPUT
    ipNeuralNetwork : ITcVnNeuralNetwork;
    ipSrcImage      : ITcVnImage;
    ipDestImage     : Reference To  ITcVnImage;
    hrPrev          : HRESULT;
END_VAR

Inputs

Name	Type	Description
ipNeuralNetwork	ITcVnNeuralNetwork	Neural network model
ipSrcImage	ITcVnImage	Source image (The image layout must be adapted to match the model's expected input format using e.g. F_VN_ConvertDataLayout or F_VN_ReshapeImage functions if necessary.)
ipDestImage	Reference To ITcVnImage	Destination image (An appropriate destination image based on the output layer is created. To process the destination image, use e.g. F_VN_ConvertDataLayout or F_VN_ReshapeImage if necessary.
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

Return value

HRESULT
