最近也在研究一些opencv4 dnn模块的工作,发现虽然用yolov3-tiny速度很快,但是明显效果跟在darknet上测试的差很多,是否是因为opencv在解析相关模型时做了一定的处理?

in yolov3_demo.cpp , how can i use the GPU??

    //检测
Mat detectionMat = net.forward("detection_out");
vector<double> layersTimings;
double freq = getTickFrequency() / 1000;
double time = net.getPerfProfile(layersTimings) / freq;
ostringstream ss;
ss << "detection time: " << time << " ms";
putText(frame, ss.str(), Point(20, 20), 0, 0.5, Scalar(0, 0, 255));

环境：win10 64 python 3.6 pycharm 2018
错误代码：

贾志刚老师你好:
请问dnn_tutorial/pedestrian_demo.cpp这个是行人检测的代码吗？我在data/models里边没有找到对应的.pb文件和.pbtxt文件,请问可以提供这两个文件吗,谢谢

性别识别准确率低
男性经常被识别为女性 。。。。

你好，
我使用您的dnn_yolov3.cpp运行时程序崩溃了，错误在net.forward(outs, outNames)这，函数内部是在LayerPin out = impl->getLatestLayerPin(pins)出错的。我这pins的size为2，pins[0]的lid=36,oid=0，pin[1]的lid=48,oid=0。
我所使用的opencv版本为4.2

您好,我们有个图像识别的小项目想请您看看.您可以看下需求,评估个价格么?
