Java怎么提升视频质量？-灵析社区

Java怎么提升视频质量，比如我有个视频，但清晰度很低。想用JavaCV或者其它库，怎么提升视频清晰度，降噪等等，谢谢。 用JavaCV试了，效果但效果不太好。 代码如下： import org.bytedeco.javacv.FFmpegFrameGrabber; import org.bytedeco.javacv.FFmpegFrameRecorder; import org.bytedeco.javacv.Frame; import org.bytedeco.javacv.FrameGrabber.Exception; import org.bytedeco.javacv.FrameRecorder; import org.bytedeco.javacv.OpenCVFrameConverter; import org.bytedeco.opencv.global.opencv_imgproc; import org.bytedeco.opencv.opencv_core.Mat; public void local(String videoFilePath) { log.info("start..."); var videoFile = new File(videoFilePath); if (!videoFile.exists()) { log.info("{}: file no exists!", videoFilePath); return; } var outputVideoFilePath = "./test.mp4"; try (FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(videoFilePath)) { // 创建FrameGrabber对象并打开视频文件 grabber.start(); // 新视频文件路径及参数 int width = grabber.getImageWidth(); int height = grabber.getImageHeight(); var frameRate = grabber.getFrameRate(); // 创建FrameRecorder对象并设置视频文件参数 FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(outputVideoFilePath, width, height); recorder.setFrameRate(frameRate); recorder.start(); // 逐帧读取视频文件 Frame frame; while ((frame = grabber.grabFrame(false, true, true, false)) != null) { // 将帧转换为OpenCV Mat OpenCVFrameConverter.ToMat converter = new OpenCVFrameConverter.ToMat(); Mat src = converter.convert(frame); // 对每一帧图像进行处理 Mat frameMat = new Mat(src); Mat denoisedMat = new Mat(); opencv_imgproc.medianBlur(frameMat, denoisedMat, 11); Mat denoisedMat1 = new Mat(); OpenCVFrameConverter.ToMat converter1 = new OpenCVFrameConverter.ToMat(); // 将处理后的每一帧图像写入新的视频文件 recorder.record(converter1.convert(denoisedMat1)); } // 关闭FrameGrabber grabber.stop(); grabber.release(); // 关闭FrameRecorder recorder.stop(); recorder.release(); log.info("If the execution is successful, the output file path: {}", outputVideoFilePath); } catch (FrameRecorder.Exception | Exception e) { throw new RuntimeException(e); } }
