There are veins in above image. I need to find out the location of pixels at which veins are present.
I tried to do this:
img=imread('segmented plus orignal image 1\aa00001.jpg');
bi=im2bw(img); imshow(bi)
But still, it is not clear.

What do you mean by "it is not clear"? Is this the result you get?

You may want to try edge detection followed by some image morphological operations (e.g. dilation, erosion) and region flood-filling.
Also, if your results from im2bw are as depicted in the comment above, the bwareaopen function may be helpful.

Has that image already been through a Hessian or Frangi filter?

You should be able to find plenty of vessel tracking papers here: http://www.visionbib.com/bibliography/contentsmedical.html#Medical%20Applications,%20CAT,%20MRI,%20Ultrasound,%20Heart%20Models,%20Brain%20Models
