Comparison of an image with others (analyze whether the chosen image is the same as the others already predefined or not)

Question

Comparison of an image with others (analyze whether the chosen image is the same as the others already predefined or not)

I am trying to make a code in Java that compares an input image with other N images already defined in the code. I developed, with help (a lot), a similar code, that compared two images only, the problem is to enlarge it. Take a single image and go out comparing with several others, I'm not knowing how to do.

What I have:

public static boolean compareImage(BufferedImage image1, BufferedImage image2){
    if (image1.getWidth()!= image2.getWidth()|| image1.getHeight() != image2.getHeight()){
        return(false);
                }
    for (int x=0; x<image1.getWidth(); x++){
        for(int y=0; y<image1.getHeight(); y++){
            if(image1.getRGB(x,y)!=image2.getRGB(x,y)){
                return(false);

You can store the images in a list, and make a loop to compare that list with the image you want, using the method of your code. Within this loop, you add a condition to do something when the comparison of the main image and some of the list returns true or false:

ArrayList<BufferedImage> imageList = new ArrayList<BufferedImage>();


for(int i = 0; i < imageList.size(); i++) {
   if(compareImage(image1, imageList.get(i))) {
      //faz algo se retornar true
   } else {
     //faz algo se retornar false
   }
}
