You need to have the Computer Vision Toolbox licensed and installed. (And you need to be using R2012a or later.)

sir，may be use R2021 version，such as

clc; clear all; close all;
faceDetector = vision.CascadeObjectDetector();
[im,map] = imread('kids.tif');
im = ind2rgb(im,map);
bbox = faceDetector.step(im);
figure; imshow(im,[]);
hold on; rectangle('position', bbox(1,:), 'EdgeColor', 'g', 'LineWidth', 2)
hold on; rectangle('position', bbox(2,:), 'EdgeColor', 'g', 'LineWidth', 2)
