Most such things are possible.
How?
Difficult to say without knowing your data and what you expect the output to be.

You have multiple blobs so multiple boundaries, each of a different length so that's why they're in a cell array. You need to extract each boundary one at a time and plot it. See this snippet. Adapt as needed.
imshow(originalImage);
title('Outlines, from bwboundaries()', 'FontSize', captionFontSize);
axis image; % Make sure image is not artificially stretched because of screen's aspect ratio.
hold on;
boundaries = bwboundaries(binaryImage);
numberOfBoundaries = size(boundaries, 1);
for k = 1 : numberOfBoundaries
thisBoundary = boundaries{k};
plot(thisBoundary(:,2), thisBoundary(:,1), 'g', 'LineWidth', 2);
end
hold off;
