// ------------------------- OpenPose C++ API Tutorial - Example 6 - XXXXXXXXXXXXX -------------------------
// If the user wants to learn to use the OpenPose library, we highly recommend to start with the
// examples in `examples/tutorial_api_cpp/`.
// This example summarizes all the functionality of the OpenPose library:
// 1. Read folder of images / video / webcam (`producer` module)
// 2. Extract and render body keypoint / heatmap / PAF of that image (`pose` module)
// 3. Extract and render face keypoint / heatmap / PAF of that image (`face` module)
// 4. Save the results on disk (`filestream` module)
// 5. Display the rendered pose (`gui` module)
// Everything in a multi-thread scenario (`thread` module)
// Points 2 to 5 are included in the `wrapper` module
// In addition to the previous OpenPose modules, we also need to use:
// 1. `core` module:
// For the Array<float> class that the `pose` module needs
// For the Datum struct that the `thread` module sends between the queues
// 2. `utilities` module: for the error & logging functions, i.e., op::error & op::log respectively
// This file should only be used for the user to take specific examples.
// Command-line user intraface
#include <openpose/flags.hpp>
// OpenPose dependencies
#include <openpose/headers.hpp>
// If the user needs his own variables, he can inherit the op::Datum struct and add them in there.
// UserDatum can be directly used by the OpenPose wrapper because it inherits from op::Datum, just define
// WrapperT<std::vector<UserDatum>> instead of Wrapper (or equivalently WrapperT<std::vector<UserDatum>>)
struct UserDatum : public op::Datum
{
bool boolThatUserNeedsForSomeReason;
UserDatum(const bool boolThatUserNeedsForSomeReason_ = false) :
boolThatUserNeedsForSomeReason{boolThatUserNeedsForSomeReason_}
{}
};
// The W-classes can be implemented either as a template or as simple classes given
// that the user usually knows which kind of data he will move between the queues,
// in this case we assume a std::shared_ptr of a std::vector of UserDatum
// This worker will just invert the image
