Remove empty image file in a ImageDatastore

I have a folder containing images, some of which are empty JPEG (Zero byte). How can I create a ImageDatastore and skip the null files?

I have tried using ReadFcn to create a custom read function, see below:

function data=readImages(filename)
    try % Fetch dimensions of a JPEG, error returned if it is null
        dim = infinfo(filename);
        data = imread(filename);
    catch error
        disp('Null data detected')  % Problem: need to define data value for this statement
    end
end

The problem with the above approach is that it doesn't really skip the null files, since I still need to define what 'data' is.

I understand you want to avoid including any empty jpg files. For reference purposes, could you please attach one of these empty jpg files? It would be helpful to come up with a solution

Hi,

To ensure only valid images are used, you can first scan the image folder and filter out any files that are 0 bytes. And while creating the “ImageDatastore” only include those verified files. This way you will only have good images in your datastore.

Hope this will be helpful!
