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.*;

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);
    }
}
