virtual bool	Infer (std::vector< FDTensor > &input_tensors, std::vector< FDTensor > *output_tensors)
	Inference the model by the runtime. This interface is included in the `Predict()` function, so we don't call `Infer()` directly in most common situation.

virtual bool	Infer ()
	Inference the model by the runtime. This interface is using class member reused_input_tensors_ to do inference and writing results to reused_output_tensors_.

virtual int	NumInputsOfRuntime ()
	Get number of inputs for this model.

virtual int	NumOutputsOfRuntime ()
	Get number of outputs for this model.

virtual TensorInfo	InputInfoOfRuntime (int index)
	Get input information for this model.

virtual TensorInfo	OutputInfoOfRuntime (int index)
	Get output information for this model.

virtual bool	Initialized () const
	Check if the model is initialized successfully.

virtual void	EnableRecordTimeOfRuntime ()
	This is a debug interface, used to record the time of runtime (backend + h2d + d2h) More...

virtual void	DisableRecordTimeOfRuntime ()
	Disable to record the time of runtime, see `EnableRecordTimeOfRuntime()` for more detail.

virtual std::map< std::string, float >	PrintStatisInfoOfRuntime ()
	Print the statistic information of runtime in the console, see function `EnableRecordTimeOfRuntime()` for more detail.

virtual bool	EnabledRecordTimeOfRuntime ()
	Check if the `EnableRecordTimeOfRuntime()` method is enabled.

virtual double	GetProfileTime ()
	Get profile time of Runtime after the profile process is done.

virtual void	ReleaseReusedBuffer ()
	Release reused input/output buffers.

Detailed Description

MODNet model object used when to load a MODNet model exported by MODNet.

Constructor & Destructor Documentation

◆ MODNet()

fastdeploy::vision::matting::MODNet::MODNet	(	const std::string &	model_file,
		const std::string &	params_file = `""`,
		const RuntimeOption &	custom_option = `RuntimeOption()`,
		const ModelFormat &	model_format = `ModelFormat::ONNX`
	)

Set path of model file and the configuration of runtime.

Parameters

[in]	model_file	Path of model file, e.g ./modnet.onnx
[in]	params_file	Path of parameter file, e.g ppyoloe/model.pdiparams, if the model format is ONNX, this parameter will be ignored
[in]	custom_option	RuntimeOption for inference, the default will use cpu, and choose the backend defined in "valid_cpu_backends"
[in]	model_format	Model format of the loaded model, default is ONNX format

Member Function Documentation

◆ Predict()

bool fastdeploy::vision::matting::MODNet::Predict	(	cv::Mat *	im,
		MattingResult *	result
	)

Predict the matting result for an input image.

Parameters

[in]	im	The input image data, comes from cv::imread(), is a 3-D array with layout HWC, BGR format
[in]	result	The output matting result will be writen to this structure

Returns: true if the prediction successed, otherwise false
