"segment out the bone-discs of the Given image"
Can you show us the ROI (use paint or any image editing tool)?

It is difficult to exactly segment out only the bone-disc area using standard segmentation techniques. The following function might help you.
function [BW] = segmentImage(X)
% X = Input image
% BW = Output binary mask for segmentation
% Auto clustering using K-means algorithm
s = rng;
rng('default');
L = imsegkmeans(single(X),2,'NumAttempts',2);
rng(s);
BW = L == 2;
% Open mask with rectangle
dimensions = [7 7];
se = strel('rectangle', dimensions);
BW = imopen(BW, se);
% Fill holes
BW = imfill(BW, 'holes');
end
