MATLAB: Error reading through all images in a directory

for loopimage acquisitionimage processingMATLAB

Hi folks,

I'm trying to loop through all images in a directory but I get an error that my file doesn't exist, despite it definitely existing and the directory being correctly specified in matlab. Below is my code, can you spot what I'm doing wrong please?

destDir = 'F:\pet images\';
imageList = dir(fullfile(destDir, '*.tif'));
destinationPathName = 'F:\crops\';
for k = 1:numel(imageList)
    
    currentImage = imageList(k).name;
    img = imread(currentImage);

The code continues from here but it won't progress past this point as this is where my error lies.

thanks!

currentImage = fullfile(imageList(k).folder, imageList(k).name);

MATLAB: How to read & display multiple images from a folder

Create a datastore by specifying the location of your image files.

location = 'E:\New Folder\*.tif';       %  folder in which your images exists
ds = imageDatastore(location)         %  Creates a datastore for all images in your folder

Loop through the datastore, read and display each image in its own window.

while hasdata(ds) 
    img = read(ds) ;             % read image from datastore
    figure, imshow(img);    % creates a new window for each image
end

MATLAB: Trying to move images to different folder based on CNN classification, and failing

I would suggest checking the return status and error messages from movefile by assigning some left hand arguments to the movefile command.

For example


    switch labelName
        case 'Anisotropy'
            [isGood,msg] = movefile(currentImage, AnisotropyClassificationPath);
        case 'Isotropy'
            [isGood,msg] = movefile(currentImage, IsotropyClassificationPath);
            % and so on
    end
    % check for errors
    if ~isGood
        disp(msg)
    end

Maybe the destination path is not formulated correctly or you have a permission issue with the destination folder

Output Arguments

collapse all

status — Move status

0 | 1

Move status, indicating if the attempt to move the file or folder is successful, returned as 0 or 1. If the attempt is successful, the value of statusis 1. Otherwise, the value is 0.

Data Types: logical

msg — Error message

character vector

Error message, returned as a character vector. If an error or warning occurs, msg contains the message text of the error or warning. Otherwise, msg is empty, ''.

msgID — Error message identifier

character vector
