如何使用OpenCV Java将视频分割成帧？

VideoCapture videoCapture = new VideoCapture("path/to/video.mp4");

Mat frame = new Mat();
while (videoCapture.read(frame)) {
    // 处理每一帧
}

Imgcodecs.imwrite("path/to/output/frame.jpg", frame);

import org.opencv.core.Mat;
import org.opencv.core.Core;
import org.opencv.videoio.VideoCapture;
import org.opencv.imgcodecs.Imgcodecs;

public class VideoFrameSegmentation {
    public static void main(String[] args) {
        // 加载OpenCV库
        System.loadLibrary(Core.NATIVE_LIBRARY_NAME);

        // 加载视频文件
        VideoCapture videoCapture = new VideoCapture("path/to/video.mp4");

        // 读取视频帧
        Mat frame = new Mat();
        int frameCount = 0;
        while (videoCapture.read(frame)) {
            // 分割帧
            Imgcodecs.imwrite("path/to/output/frame_" + frameCount + ".jpg", frame);
            frameCount++;
        }

        // 释放资源
        videoCapture.release();
    }
}
