A file does not appear
显示 更早的评论
I have a code that fetches the files about images from a folder. However, if I put two files it only returns 1 and not both. If I want to go to a directory and have two subfolders and want to get files from one folder and the other folder how can I do it?
clc;
close all;
clear;
workspace;
fontSize = 10;
imagePath = uigetdir('c:\');
imageFiles = [dir(fullfile(imagePath,'*.jpeg')); dir(fullfile(imagePath,'*.TIF')); dir(fullfile(imagePath,'*.PNG'))];
files = size({imageFiles.name},2);
filename = {imageFiles.name};
for i=1:files
f = fullfile(imagePath,char(filename(i)));
image= imread(f);
imshow(image)
FT=fft2(image);
magnitude=abs(fftshift(FT));
end

This works well for me for multiple images. Is it possible that your images have different extensions other than "jpeg", "tif" or "png"? For instance, this doesn't capture "jpg" images.

The problem is that if I want to do the FFT it only does it from one image and not from several images..
two images should appear and not just one

@PEDRO ALEXANDRE Ferna - I'm not sure I understand. Isn't your above screen shot just showing the value for f which is a variable within your loop? Have you confirmed that imageFiles has only one file?
"two images should appear and not just one"
You made no attempt to tile the images or save them or something similar, so on every iteration you simply discard the previous image so in the end you will only see the final image.
You also make no attempt to store FT nor magnitude, so these will also be overwritten on every loop iteration except the last one.
P = uigetdir('c:\');
S = [... much clearer than squeezing everything onto one line:
dir(fullfile(P,'*.jpeg'));...
dir(fullfile(P,'*.TIF'));...
dir(fullfile(P,'*.PNG'))];
for k = 1:numel(S); % better to use NUMEL()
F = fullfile(P,S(k).name);
I = imread(F);
imshow(I) % discarted except the last one
FT = fft2(I) % discarded except the last one
magnitude = abs(fftshift(FT)) % discarded except the last one
end
