Hi
I have the following result of segmentation
How can I improve the results?
1) I want to improve the appearance to get the vessels more smooth.
2) I want to extract the oval-like part of the vessels in the middle of the image.
Any suggestions?

For your first question:
Is this strictly for appearances? If so, does medfilt2 do what you want?
rawImg = rgb2gray(imread('seg_vessel.jpg'));
nbhd = [2 2]; %play around with neighborhood size to get the smoothness you want
smoothedImg = medfilt2(rawImg,nbhd);
figure;imagesc(rawImg); colormap(gray)
figure;imagesc(smoothedImg); colormap(gray)

inputImage = imread('seg_vessel.tif');
grayImage = rgb2gray(inputImage);
binaryImage = im2bw(grayImage,level);
[B,W,D,T] = bwboundaries(binaryImage);
imshow(W)
Hi Kindly Look into the code, this might be the result which you had expected

Sorry Use this one

You can use imopen() to snip off pointy parts or use imclose() to blur out the boundary.
