what are your opinions to modify this code for improvement the result?

my image is at this link: <http://tinypic.com/view.php?pic=5wh0lg&s=5>

i want to implement contrast enhancement, thresholding, morphological opening, Edge detection, morphological erosion and skeketonization

i wrote the below code , but the result was not enoughly suitable for me.

so what are your proposals to obtain best result ?. also if i want to do local thresholding how can i do it ? what will change in thresholding step?.

m=imread();

%%%%%1-Contrast enhancement%%%

x=adapthisteq(m);

%%%%%%2-global thresholding%%%%%%
level=graythresh(x);
m1=im2bw(x,level);

%%%%3-Morphological opening%%%%%%%
BW2 = bwmorph(m1,'open');

%%%%%%%%%%4-Sobel Edge detector%%%%%%
w=fspecial('sobel');
edge=imfilter(BW2,w,'replicate');

%%%5-morphological erosion%%%%%%%%
BW3 = bwmorph(edge,'erode');
%%%6-morphological skeketonization%%%%%%
W3 = bwmorph(BW3,'skel') ;

% displaying images%%%
figure,imshow(m);
figure,imshow(x);
figure,imshow(m1);
figure,imshow(BW2);
figure,imshow(edge);
figure,imshow(BW3);
figure,imshow(W3);

thank you

We do not know what _would_ be "suitable enough for you".

Past discussions about this project tend to suggest to us that you are hoping to extract more information than is present in the image.

[mmm ssss]

yes, this is right Mr.Walter.

do you have any modications to the above code?

I would rename your variable edge to a name that doesn't overwrite the IPT stock function edge().
