I have this image and i would like to produce a colormap.
this is an edge detected image of a crack on concrete. I have already found the distances and coordinate points between each pixel. Now what I would like to do is create a colormap between the edges showing according to the crack opening distances.
Any ideas of how I can go about doing this?
I've thought about plotting straight lines with different line colors but it doesn't look as nice.

Display, with imshow(), the distance map of the region in between the lines. Use caxis() to tell it what value each end of the colormap should correspond to. Then create a colormap to correspond to the distances, e.g. jet(256). Then call colormap(yourColorMap). For example (untested)
imshow(distanceMapImage, []);
axis on;
caxis([0, 10]);
colormap(jet(256));
colorbar;
Post your distance map if you can't figure it out.

Then you need to get a binary image of just branches. Solid, not outlines. You can do this by connecting the open ends and calling imfill. Then call bwdist() and colormap().
