How can I access each superpixel of an image?

Hello

I have successfully segmented the superpixels of an image (having size 120x160) using SLIC algorithm. For instance,

segments = vl_slic(img,regionSize, regularizer);

This segments(having size 120x160) contain all the number of superpixels which are segmented from img using SLIC. And I segmented only 50 superpixels.

Now how can I access each superpixel from this segments?

For example, I want to make a cell array (let say l=cell(1,num_superpixels)) and keep all individual superpixels in each cell for further processing.

Any help is appreciated

Thanks in advance!

segmented_images = cell(1,max(max(L)));

rgb_label = repmat(L,[1 1 3]);

for k = 1:max(max(L)) %L-label matrix

color = im;%im-Color img

color(rgb_label ~= k) = 0; segmented_images{k} = color; end

imshow(segmented_images{1}), title('objects in cluster 1');% this will display your Superpixel or cluster no 1, %this way you can view your individual superpixel %check segmented_images in workspace you will find cell arrays.

what is 'im'?

idx=label2idx(L); and then you can use idx{i} to search each superpixel
