HOGDescriptionr的使用问题

Problems using HOGDescriptor

本文关键字：问题 HOGDescriptionr      更新时间：2023-10-16

我在摆弄一些c++/occv。我在看一些样品，还没有设法编译/运行使用HOGDescriptor的peopledetect.cpp。

我已经设置了一个基本的Qt控制台应用程序来测试和缩小问题范围，并获得了以下基本代码：

#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include "opencv2/imgproc/imgproc.hpp"
#include "opencv2/objdetect/objdetect.hpp"
#include <stdio.h>
#include <string.h>
#include <ctype.h>
using namespace cv;
using namespace std;
int main(){
    Mat img = imread("../images/people1.jpg");
    HOGDescriptor hog;
    namedWindow("people detect test");
    imshow("TaDa!",img);
    waitKey(5000);
    return 1;
}

由于以下行而无法编译：HOGDescriptor hog;。以下是Qt给出的编译输出：

不幸的是，当谈到c++/opencv时，我是一个n00b，所以不确定是什么错误的确切含义以及如何修复。提示/提示？

您需要链接到libopencv objdetect。2.3.1
