你好，代码供参考，如有帮助还望题主给个宝贵的采纳支持一下答主答题哟（点击下方“采纳该答案”），谢谢啦（づ￣3￣）づ╭❤～

I = imread('test.jpg'); % 按照文件名读入图片文件，记的要把你的图像文件放在当前文件夹哟
I1 = double(I)/256;
figure(1);clf
imshow(I); title('换背景之前')
% 换背景
R = I1(:,:,1);
G = I1(:,:,2);
B = I1(:,:,3);
q = (R-1).^2+G.^2+B.^2<0.5^2;
R2 = I(:,:,1); G2 = I(:,:,2); B2 = I(:,:,3); 
R2(q) = uint8(0);
G2(q) = uint8(0);
B2(q) = uint8(255);
I2 = I;
I2(:,:,1) = R2; I2(:,:,2) = G2; I2(:,:,3) = B2; 
figure(2);clf
imshow(I2); title('换背景之后')
%% 下面开始排版
[m,n,p] = size(I2);
bn = floor(m/40); % 边缘宽度
k1 = 2; k2=3; % 2x3排版
I3 = uint8(255*ones(m*k1+2*bn*k1, n*k2+2*bn*k2, p));
for i = 1:1:k1
    for j = 1:1:k2
        x1 = bn + (i-1)*m + 2*bn*(i-1) + 1;
        y1 = bn + (j-1)*n + 2*bn*(j-1) + 1;
        x2 = x1 + m -1;
        y2 = y1 + n -1;
        I3(x1:x2, y1:y2,:) = I2;
    end
end
figure(3);clf
imshow(I3); title('排列之后')

效果（这里使用的是网上搜的一张图）：
