How can I access each superpixel of an image?

1 次查看(过去 30 天)
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.

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