I have a medial axis on which each pixel is specified with a certain value. I am going to increase the thickness of my line according to these values. for example, where the value is 23 the code make 11 pixels in each side of the center pixel (11+1+11 =23) or where is 12 it create 6 pixels in one side and 5 pixels on the other side of the center pixel to give me 12-pixel width.
Cheers

How did you get the medial axis? Normally it comes from a binary image where the width is what you're trying to do. So you should already have what you want. If not, show us your gray scale image, your binary image, and your distance transform.

Yes, it was for 3.5 years ago. Image Analyst is right. Each pixel has a value (say 0-100) and the line/pixel needs to be widen according to that value. For example if the value of a pixel is 5, 5 pixel should be there, i.e. including the pixel itself 2 pixels needs to be added in each side (2+2+1=5).

you can change this image to binary, find ones and making each one double!

By "the thickness of my line according to these values" I think he meant to not simply widen the line by 2 at each point in the binary image, but to widen it according to some factor times the Gray Level of the original gray scale image. But since it's been 3.5 years since then, I don't think he cares anymore.
