YOLO5Face.lite.ai.toolkit

使用 🍅🍅 Lite.AI.ToolKit C++工具箱来跑YOLO5Face人脸检测(带关键点)的一些案例(https://github.com/DefTruth/lite.ai.toolkit) , 包含ONNXRuntime C++、MNN、TNN和NCNN版本。

如果觉得有用，不妨给个Star⭐️🌟支持一下吧~ 🙃🤪🍀

2. C++版本源码

YOLO5Face C++ 版本的源码包含ONNXRuntime、MNN、TNN和NCNN四个版本，源码可以在 lite.ai.toolkit 工具箱中找到。本项目主要介绍如何基于 lite.ai.toolkit 工具箱，直接使用YOLO5Face来跑人脸检测。需要说明的是，本项目是基于MacOS下编译的 liblite.ai.toolkit.v0.1.0.dylib 来实现的，对于使用MacOS的用户，可以直接下载本项目包含的liblite.ai.toolkit.v0.1.0动态库和其他依赖库进行使用。而非MacOS用户，则需要从lite.ai.toolkit 中下载源码进行编译。lite.ai.toolkit c++工具箱目前包含70+流行的开源模型，就不多介绍了，只是平时顺手捏的，整合了自己学习过程中接触到的一些模型，感兴趣的同学可以去看看。

ONNXRuntime C++、MNN、TNN和NCNN版本的推理实现均已测试通过，欢迎白嫖~

4. 接口文档

在lite.ai.toolkit 中，YOLO5Face的实现类为：

class LITE_EXPORTS lite::cv::face::detect::YOLO5Face;
class LITE_EXPORTS lite::mnn::cv::face::detect::YOLO5Face;
class LITE_EXPORTS lite::tnn::cv::face::detect::YOLO5Face;
class LITE_EXPORTS lite::ncnn::cv::face::detect::YOLO5Face;

该类型目前包含1公共接口detect用于进行目标检测。

public:
    /**
     * @param mat cv::Mat BGR format
     * @param detected_boxes_kps vector of BoxfWithLandmarks to catch detected boxes and landmarks.
     * @param score_threshold default 0.25f, only keep the result which >= score_threshold.
     * @param iou_threshold default 0.45f, iou threshold for NMS.
     * @param topk default 400, maximum output boxes after NMS.
     */
    void detect(const cv::Mat &mat, std::vector<types::BoxfWithLandmarks> &detected_boxes_kps,
                float score_threshold = 0.25f, float iou_threshold = 0.45f,
                unsigned int topk = 400);

detect接口的输入参数说明：

mat: cv::Mat类型，BGR格式。
detected_boxes_kps: BoxfWithLandmarks向量，包含被检测到的框box(Boxf)，box中包含x1,y1,x2,y2,label,score等成员; 以及landmarks(landmarks)人脸关键点(5个)，其中包含了points，代表关键点，是一个cv::point2f向量(vector);
score_threshold：分类得分（质量得分）阈值，默认0.25，小于该阈值的框将被丢弃。
iou_threshold：NMS中的iou阈值，默认0.3。
topk：默认400，只保留前k个检测到的结果。

5. 使用案例

这里测试使用的是yolov5face-n-640x640.onnx(yolov5n-face)nano版本的模型，你可以尝试使用其他版本的模型。

    std::cout << "TNN Version Done! Detected Face Num: " << detected_boxes.size() << std::endl;
    
    delete yolov5face;
#endif
}

static void test_ncnn()
{
#ifdef ENABLE_NCNN
    std::string param_path = "../hub/ncnn/cv/yolov5face-n-640x640.opt.param"; // yolov5n-face
    std::string bin_path = "../hub/ncnn/cv/yolov5face-n-640x640.opt.bin";
    std::string test_img_path = "../resources/1.jpg";
    std::string save_img_path = "../logs/1.jpg";
