Use bwboundaries to extract boundaries. The first output of it will be a cell array, one entry for each region found. Pass the contents of each entry in the cell array to the chaincode routine at http://www.mathworks.com/matlabcentral/fileexchange/29518-freeman-chain-code
B = bwboundaries(YourImage);
numregions = length(B);
chains = cell(numregions,1);
for blobnum = 1 : numregions
chains{blobnum} = chaincode(B{blobnum});
end
