How can I read a batch of images instead of a single image, cluster them and pick the desired clusters for the segmented images for further analysis?

I am using the following code for the segmentation of images which has rash on the skin which can segment only a single image. I want to find a way to read a batch of images instead of a single image and pick the desired clusters for further analysis.
I have attached two images for testing.
Help me please!
I = imread(['ColorSpace\ForExperiment\foot.jpg']);
lab_he = rgb2lab(I);
% Extract first channel (L)
ab = lab_he(:, :, 2:3);
% Convert to data type single
ab = im2single(ab);
% Perform clustering using K-Means
nColors = 4;
pixel_labels = imsegkmeans(ab, nColors, "NumAttempts", 5);
imshow(pixel_labels, []);
% Display each cluster with their objects
mask1 = pixel_labels == 1;
cluster1 = I .* uint8(mask1);
imshow(cluster1); title('Objects in cluster1');
% Display second cluster's objects
mask2 = pixel_labels == 2;
cluster2 = I .* uint8(mask2);
imshow(cluster2); title('Objects in cluster2');
% Display third cluster's objects
mask3 = pixel_labels == 3;
cluster3 = I .* uint8(mask3);
imshow(cluster3); title('Objects in cluster3');
% Display fourth cluster's objects
mask4 = pixel_labels == 4;
cluster4 = I .* uint8(mask4);
imshow(cluster4); title('Objects in cluster4');

To process a folder of images, put your code inside a loop over files. See the FAQ for code samples:

Thank you very much for your reply. You helped my alot and as I reviewed many different questions in forum, your asnwers were the most applicable ones.
I am able to read multiple images and give them as input the the code written above but the problem is that how can I get the clusters for multiple images with the KMeans algorithm?, for example if I read 3 images and input them to the KMeans with 4 clusters written above, so how can I display the 1st cluster, the 2nd cluster, the 3rd cluster and the 4th cluster for 3 input images.
