I had segmented image and want to detect of these pixels by extracting all pixels that do not have the same label in their 3×3 neighborhood (N_ns), and then re-classify of these extracted pixels using local information in a 5×5 neighborhood (N_rl). What can I do? Thanks..

labelsYouWantToKeep = [3,5,9]; % Whatever blob numbers you want.
% Get a new labeled image with only those blobs in it.
newLabeledImage = ismember(originalLabeledImage, labelsYouWantToKeep);
imshow(newLabeledImage, []); % Display it.
% Remeasure with only those blobs in the image.
newMeasurements = regionprops(newLabeledImage);

Explain more of what you want to do, especially about what you want to do with blobs based on what is in their "neighborhood". Say blob #15 and blob #27 have their centroids or perimeters within 9 pixels of each other - now what????
