MATLAB: How to add images continuously to a imageDatastore

Question

Hi,

I'm new to the Matlab and using a imageDatastore object to store images comming from a camera, I want to update an existing image data store continuously. Is there a way to do that…?

Thanks..

Since the ‘Files’ and ‘Labels ‘ properties of the imageDatastore function return cell array of character vectors, you can directly use these to append/concatenate using the cat function.

For example:

imds = imageDatastore({'street1.jpg','street2.jpg','peppers.png','corn.tif'}); % Existing datastore 
imds_new = imageDatastore({'cameraman.tif'}); %to append to the existing datastore 
imds_cat = imageDatastore(cat(1, imds.Files, imds_new.Files)); 
imds_cat.Labels = cat(1, imds.Labels, imds_new.Labels) 
imds = imds_cat;
