javacv图片美颜处理，视频美颜处理

国产剧明星演戏自带十级滤镜，是众所周知的秘密；
使用opencv也能实现一定的美颜效果：

一、图片美颜

代码

package top.lingkang.test.demo;import org.bytedeco.opencv.opencv_core.*;
import org.bytedeco.opencv.opencv_imgproc.*;import java.io.File;import static org.bytedeco.opencv.global.opencv_core.*;
import static org.bytedeco.opencv.global.opencv_imgcodecs.*;
import static org.bytedeco.opencv.global.opencv_imgproc.*;/*** @author lingkang* Created by 2022/6/6*/
public class Demo01 {public static void main(String[] args) {Mat result = new Mat();Mat image = imread("C:\\Users\\Administrator\\Desktop\\temp\\2.png");int level = 18;// 值越大，过滤强度越大bilateralFilter(image, result, level, level * 2, level / 2);File out = new File("d:/2.png");if (out.exists())out.delete();imwrite(out.getPath(), result);}
}

二、视频美颜
