硒/ JAVA图像比较

Question

目前，我的代码需要一些分辨率的屏幕截图。我想将所有图像与最后捕获的图​​像进行比较。

我的截图截图代码，现在我想做一些事情，将其与分辨率文件夹和当前图像文件夹的最后一个列表进行比较，并生成图像，程序会在其中标记出不同之处。将提供任何帮助。

Answer 1

签出OpenCV库。 您可以在那里找到所需的东西。 在这里看看如何比较图像的示例。

Answer 2

检查此链接：

https://www.frontendtest.org/blog/screenshot-comparison/

这些家伙创建了自己的用于比较图像的库，它具有您正在谈论的功能。

要使用全部内容，几乎不需要重构，但是您可以检查它们如何基于原始图像生成新图像，并用红色矩形标记更改。

下面的代码在图像坐标上绘制了一个红色矩形：X 100px，Y 100px（从左上角开始）； 矩形大小：宽度50像素，高度50像素；

    import java.awt.*;
    import java.awt.image.BufferedImage;
    import java.io.IOException;
    import javax.imageio.ImageIO;

    public boolean drawRectangle(BufferedImage img, String pathOut) throws IOException {                            
        imgOut = imageToBufferedImage(ImageIO.read(new File(img)));
        Graphics2D outImgGraphics = imgOut.createGraphics();
        outImgGraphics.setColor(Color.RED);
        outImgGraphics.drawRect(100, 100 , 50, 50);
        saveImage(imgOut,pathOut);
    }

    private BufferedImage imageToBufferedImage(Image img) {
            BufferedImage bi = new BufferedImage(img.getWidth(null),
                img.getHeight(null), BufferedImage.TYPE_INT_RGB);
            Graphics2D g2 = bi.createGraphics();
            g2.drawImage(img, null, null);
            return bi;
    }
