Hi Imran,

I understand that you want to apply resize operation on multiple images.

You can pile up the images in an ‘imageDatastore’.

After building the ‘imageDatastore’, use ‘transform’ function with a helper function which entails the required resizing operations.

Here is an example of implementing it:

imds=imageDatastore(["bug1.png","bug2.png"]);

targetSize = [224,224];

imdsReSz = transform(imds,@(x) imresize(x,targetSize));

I=read(imdsReSz);

imshow(I)

Hope it resolves your query.
