视频去水印

视频去水印，但是还会模糊，有大佬看到可以指点一下。

        String inputVideoPath = "E:\\my\\mengbao\\2024\\1221\\1.mp4";
        String outputVideoPath = "E:\\my\\mengbao\\2024\\1221\\8-copy.mp4";

        // 打开视频
        VideoCapture video = new VideoCapture(inputVideoPath);
        if (!video.isOpened()) {
            System.out.println("无法打开视频文件，请检查路径！");
            return;
        }

            Mat kernel = new Mat(3, 3, CvType.CV_32F);
            kernel.put(0, 0, 0, -1, 0,
                    -1, 5, -1,
                    0, -1, 0); // 锐化卷积核
            Imgproc.filter2D(roi, sharpenedRoi, -0, kernel);


            // 将处理过的区域替换回原图像
            sharpenedRoi.copyTo(inpaintedFrame.submat(watermarkArea));

            // 4. 写入处理后的帧到输出视频
            writer.write(inpaintedFrame);
        }

        // 释放资源
        video.release();
        writer.release();
        System.out.println("视频去水印处理完成！");
    }
