Multiple Image reconstruction with real and imaginary part in 2d array

2 visualizaciones (últimos 30 días)
I have two mat files one with real and another with imaginary part of 500 images. I am using the following line to reconstruct a single image :
" imshow(reshape(sqrt(a_imag(:,i).^2+a_real(:,i).^2),[128,128]) "
Each mat file is a 2D array (16384x500) with grayscale images of size 128x128. 'i' indiactes the image/column number.
I am trying to reconstruct all the 500 images and save each of them in .jpg format in the same order from 1-500. I tried this code and I am recieving an error.
a_real = load("img_real.mat");
a_imag = load("img_imag.mat");
for i = 1 : 500
I(:,i) = reshape(sqrt(a_imag(:,i).^2+a_real(:,i).^2),[128,128]);
save('image', num2str(i),'.jpg');
Operator '.^' is not supported for operands of type 'struct'.
Error in image_recon (line 6)
I(:,i) = reshape(sqrt(a_imag(:,i).^2+a_real(:,i).^2),[128,128]);

What is the name of the variable stored inside the .mat files? If I assume it is X, then,
a_real = load("img_real.mat").X;
a_imag = load("img_imag.mat").X;

a_real = load("img_real.mat").img_real;
a_imag = load("img_imag.mat").img_imag;
I = reshape( sqrt(a_imag.^2+a_real.^2), 128,128,[]);
for i=1:N
a = imread('image99.jpg');
