图像相似度

解题思路:

注意事项:

参考代码:

public class Main {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        int m = scanner.nextInt();

        int n = scanner.nextInt();

        int[][] image1 = new int[m][n];

        int[][] image2 = new int[m][n];

        // 读入第一张图像

        for (int i = 0; i < m; i++) {

            for (int j = 0; j < n; j++) {

                image1[i][j] = scanner.nextInt();

            }

        }

        // 读入第二张图像

        for (int i = 0; i < m; i++) {

            for (int j = 0; j < n; j++) {

                image2[i][j] = scanner.nextInt();

            }

        }

        // 计算相同像素点数

        int sameCount = 0;

        for (int i = 0; i < m; i++) {

            for (int j = 0; j < n; j++) {

                if (image1[i][j] == image2[i][j]) {

                    sameCount++;

                }

            }

        }

        // 计算相似度并输出结果

        double similarity = (double)sameCount / (m * n) * 100;//强制类型转换

        System.out.printf("%.2f", similarity);

    }
