有没有办法使用jimp for node js来比较两个图像？

const Jimp = require('jimp');

async function compareImages(imagePath1, imagePath2) {
  try {
    const image1 = await Jimp.read(imagePath1);
    const image2 = await Jimp.read(imagePath2);

    if (image1.bitmap.width !== image2.bitmap.width || image1.bitmap.height !== image2.bitmap.height) {
      throw new Error('Images must have the same dimensions');
    }

    let totalDifference = 0;
    const width = image1.bitmap.width;
    const height = image1.bitmap.height;

    for (let x = 0; x < width; x++) {
      for (let y = 0; y < height; y++) {
        const pixel1 = image1.getPixelColor(x, y);
        const pixel2 = image2.getPixelColor(x, y);
        const difference = Jimp.intToRGBA(pixel1).r + Jimp.intToRGBA(pixel2).r +
                          Jimp.intToRGBA(pixel1).g + Jimp.intToRGBA(pixel2).g +
                          Jimp.intToRGBA(pixel1).b + Jimp.intToRGBA(pixel2).b;
        totalDifference += Math.abs(difference);
      }
    }

    const averageDifference = totalDifference / (width * height * 3);
    return averageDifference;
  } catch (error) {
    console.error('Error comparing images:', error);
    return null;
  }
}

// 使用示例
compareImages('path/to/image1.jpg', 'path/to/image2.jpg')
  .then(difference => {
    console.log('Average Pixel Difference:', difference);
  });

if (image1.bitmap.width !== image2.bitmap.width || image1.bitmap.height !== image2.bitmap.height) {
  image2.resize(image1.bitmap.width, image1.bitmap.height);
}
