MATLAB: To seperate object at foreground from background with boundary

bakcgroundforegroundwanted object;bounderies

Hi all
   if true
    % code
  end
thresh=+(gri>113);
imshow(thresh);
BW2 = imcomplement(thresh);
figure;imshow(BW2);
bw2 = imfill(BW2, 'holes');
figure;imshow(bw2);
labeledImage = bwlabel(bw2);
st=regionprops(labeledImage,'area','Perimeter');
% Get areas and perimeters of all the regions into single arrays.
allperi = [st.Perimeter];
% Find objects that have "preim" values of big perimetiry.
bigObjects = find(allperi > 2500); % Whatever value you want.
% labeledImage1 = bwlabel(bigObjects);
% figure;imshow(labeledImage1);
% Compute new binary image with only the big perim objects in it.
bI = ismember(labeledImage, bigObjects) > 0;
figure;imshow(bI);
img1 = uint8(255.*bsxfun(@times,im2double(gri),bI));
figure;imshow(img1);
The code is above. I want to take only foregorund object to find features from that but boundaries only get How can I get the object with inside features like second image.

I done it like in figure. NOw how can I only extract features from only wanted object.
