计算miou完整代码

下面是计算MIOU的完整代码：

#include <iostream>
#include <string>
#include <opencv2/opencv.hpp>

double MIOU(cv::Mat image_ground, cv::Mat image_daice) {
    double jiaoji = 0.0;
    double duli_ground = 0.0;
    double duli_daice = 0.0;
    double bingji = 0.0;
    double iou = 0.0;

    for (int i = 0; i < image_ground.cols; i++) {
        for (int j = 0; j < image_ground.rows; j++) {
            if ((image_ground.at<uchar>(j, i) == 255) && (image_daice.at<uchar>(j, i) == 255))
                jiaoji += 1.0;

            if (image_ground.at<uchar>(j, i) == 255)
                duli_ground += 1.0;

            if (image_daice.at<uchar>(j, i) == 255)
                duli_daice += 1.0;
        }
    }

    bingji = duli_ground + duli_daice - jiaoji;
    iou = (double)(jiaoji / bingji);

    return iou;
}

int main() {
    double sum = 0.0;
    double miou = 0.0;

    for (int i = 0; i <= 99; i++) {
        cv::Mat image_ground = cv::imread("C:/Users/Desktop/数据集/" + std::to_string(i) + ".png", CV_LOAD_IMAGE_GRAYSCALE);
        cv::Mat image_daice = cv::imread("C:/Users/Desktop/开发工程/" + std::to_string(i) + "_threshold.png", CV_LOAD_IMAGE_GRAYSCALE);

        double iou_meige = MIOU(image_ground, image_daice);
        sum += iou_meige;
    }

    miou = sum / 100.0;
    std::cout << "MIOU: " << miou << std::endl;

    return 0;
}
