Create a datastore that maintains parity between the pair of images of the underlying datastores. For instance, create two separate image datastores, and then create a combined datastore that reads corresponding images from the two image datastores.

Create a datastoreimds1representing a collection of three images.

imds1 = imageDatastore({'street1.jpg','street2.jpg','peppers.png'});

Create a second datastoreimds2by transforming the images ofimds1to grayscale images.

imds2 = transform(imds1,@(x) im2gray(x));

Create a combined datastore fromimds1andimds2.

imdsCombined = combine(imds1,imds2);

Read the first pair of images from the combined datastore. Each read operation on this combined datastore returns a pair of images represented by a1-by-2cell array.

dataOut = read(imdsCombined)

dataOut=1×2 cell array{480x640x3 uint8} {480x640 uint8}

Display the output of the first read from the combined datastore.

imshow(imtile(dataOut));
