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);
