Question

在某一范围内将tire.tif和rice.tif两图像相加。matlab，怎么相加，相减显示？

Answer 1

可以使用imread来直接读取，比如：% By lyqmath
clc; clear all; close all;
I1 = imread('tire.tif');
I2 = imread('rice.png');
I2 = imresize(I2, size(I1));
I3 = imadd(I1, I2);
figure;
subplot(1, 3, 1); imshow(I1, []);
title('tire.tif By lyqmath', 'FontWeight', 'Bold', 'Color', 'r');
subplot(1, 3, 2); imshow(I2, []);
title('rice.png By lyqmath', 'FontWeight', 'Bold', 'Color', 'r');
subplot(1, 3, 3); imshow(I3, []);
title('求和图像 By lyqmath', 'FontWeight', 'Bold', 'Color', 'r');结果
