Hi..

I have just start to use ImageJ, so I have no idea if I can do what I
want. I hope someone knows if it is possible and how. I have some
images- that I want to substract the diffuse reflection from and only
have the specular reflection in the final image. The images is a
result from scanning some boards. Here is one of the images:

The "black hole" is missing data.....

The reason why I want to substract the diffuse reflection is that I
think it is easier to be able to see the fiber orientation in the
wood.

Thanks in advance
