GaussianBlur(帧,帧,大小(10,10), 1.0);错误：“大小”未在此范围内声明

Question

一段时间后返回C ++，无法通过此错误解决问题。请帮忙。

#include "opencv2/highgui/highgui.hpp"
#include <opencv2/imgproc.hpp>
#include <opencv2/core/types.hpp>
#include <iostream>


int main() {
    constexpr int device_id = 0;
    cv::VideoCapture input_stream(device_id);

    if (!input_stream.isOpened()) {
        std::cerr << "Could not open camera" << std::endl;
        return EXIT_FAILURE;
    }

    const std::string window_title = "CT";

    cv::namedWindow(window_title, cv::WINDOW_GUI_NORMAL);
    cv::Mat frame;

    while (true) {
        input_stream >> frame;
        if (frame.empty()) {
            std::cerr << "The camera returned an empty frame, please check the camera" << std::endl;
            break;
        }
        GaussianBlur(frame, frame, Size(10,10), 1.0);
        //blur(frame, blurredFrame, Size(3,3));
        //cv::imshow(window_title, frame);
        cv::imshow(window_title , frame);

        constexpr int delay_ms = 15;
        if (cv::waitKey(delay_ms) >= 0) { break; }
    }

    return EXIT_SUCCESS;
}

错误：在此范围内未宣布“大小”，

GaussianBlur(frame, frame, Size(10,10), 1.0);

预计将获得高斯布鲁结果

P.S.似乎解决方案是使用CV ::大小

PS似乎解决方案只是使用CV ::大小
