Hello every one,
I have one hand image(binary), which after doing segmentation i got the image with edges and now i want to fill inside of the hand which can see in the second following image.
I used imfill but it didnt change anything.
I will appreciate if anyone can help me to do it.
thanks

You need to draw a line across the bottom to close off the arm before you fill it.
% Make tempoprary line.
binaryImage(end, :) = true;
% arm is sealed off. Now we can fill.
binaryImage = imfill(binaryImage, 'holes');
% Erase temporary line.
binaryImage(end,:) = false;

You must have an old version of MATLAB where bwareafilt() had not been introduced yet. See my attached demo where you can use your version and use my function ExtractLargestNBlobs.
To smooth the boundary you can use imclose() or activecontour() (demo attached).

Not sure what you did but it works just great with my ExtractNLargestBlobs() function. No problems whatsoever. Working code is attached.

Sometimes you need to save the line, then do your fill or whatever, then set it back:
% Save existing line:
originalLine = binaryImage(1, :);
% Make temporary line along the top of the image.
binaryImage(1, :) = true; % Set all of row 1 to true/white/1
% Now do some processing, such as imfill() or whatever...
% Finally restore original line:
binaryImage(1, :) = originalLine;
