The NNStreamer Single API provides interfaces to invoke a neural network model with a single instance of input data.

Required Header

#include <nnstreamer/nnstreamer-single.h>

Overview

The NNStreamer Single API provides interfaces to invoke a neural network model with a single instance of input data. This function is a syntactic sugar of NNStreamer Pipeline API with simplified features; thus, users are supposed to use NNStreamer Pipeline API directly if they want more advanced features. The user is expected to preprocess the input data for the given neural network model.

This function allows the following operations with NNStreamer:

• Open a machine learning model with various mechanisms.
• Close the model.
• Interfaces to enter a single instance of input data to the opened model.
• Utility functions to get the information of opened model.

Note that this function set is supposed to be thread-safe.
