Question

用MATLAB编程，详细代码怎么写？

Read the original image you made in last homework with Matlab
Get the real part& imaginary part, magnitude and phase angle of the complex number
Save the result images with ‘jpg’ format

Read two gray images
Get the magnitude and phase angle based on the fft2 results for both images
Exchange the magnitude images and reconstruct the images based on the new magnitude and old phase angle
Save the result images with ‘jpg’ format

Answer 1

a=imread(‘图片路径’)%读图片
b=double(a);%可以把0-255的值转化为0-1的实数值
write('目的路径',b)%可以把修改后的图片存到指定目录，扩展名可以直接写到名字里。（若只写名字则表示当前目录）。
%读灰度图像与彩色图像相同。matlab默认会按照最大灰度值来存，怎么该不知道。
保存灰度图像与彩色图像相同。
