Java如何识别照片颜色？

import javax.media.jai.JAI;
import javax.media.jai.PlanarImage;
import java.awt.*;
import java.awt.image.RenderedImage;
import java.awt.image.renderable.ParameterBlock;

public class ColorRecognition {
    public static void main(String[] args) {
        // 加载图像
        String imagePath = "path_to_image.jpg";
        RenderedImage image = JAI.create("fileload", imagePath);

        // 获取图像的颜色信息
        Histogram histogram = getColorHistogram(image);

        // 打印颜色信息
        for (int i = 0; i < histogram.getNumBins(); i++) {
            System.out.println("Color " + i + ": " + histogram.getBinValue(i));
        }
    }

    private static Histogram getColorHistogram(RenderedImage image) {
        // 创建颜色直方图参数
        ParameterBlock pb = new ParameterBlock();
        pb.addSource(image);
        pb.add(null);
        pb.add(1);
        pb.add(1);
        pb.add(new int[]{256});
        pb.add(new int[]{256});
        pb.add(new double[]{0});
        pb.add(new double[]{256});

        // 计算颜色直方图
        PlanarImage histogramImage = JAI.create("histogram", pb);
        Histogram histogram = (Histogram) histogramImage.getProperty("histogram");

        return histogram;
    }
}
