How can we implement image parsing in JPEG format using…

To achieve JPEG image parsing, one can utilize image processing libraries in C++, such as OpenCV, to read and parse JPEG files.

Here is a simple example code demonstrating how to use the OpenCV library to parse JPEG format images:

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

int main() {
    // 读取JPEG文件
    cv::Mat image = cv::imread("input.jpg", cv::IMREAD_COLOR);
    
    if (image.empty()) {
        std::cerr << "Failed to read image file." << std::endl;
        return -1;
    }
    
    // 显示图片
    cv::imshow("JPEG Image", image);
    cv::waitKey(0);
    
    return 0;
}

In the example code above, the imread function is used to read a JPEG file, the imshow function is used to display the image that was read, and the waitKey function is used to wait for the user to press a key on the keyboard.

You can further manipulate and process the analyzed image according to your own needs.
