Dear Listers,

I need advice on how to conduct a texture analysis of tree bark (trembling
aspen, or Populus tremula).

I have a set of 300 raw images taken at a specific distance from each tree,
with a region of interest of 500x500 pixels selected for the analysis.
The trees are all the same species but grow in clones which have differences
in certain physical characteristics - one of which seems to be bark texture.
 I can recognise these differences by eye, but I would like to quantify the
differences in a sound and scientifically robust way.

Since I am new to imageJ and digital image analysis, I don't really know how
I should proceed, and I have read of a range of methods for this type of work.
Would anyone have suggestions or recommendations on how to begin?  I believe
I need to standardise the images first, then do an analysis of some
description - any ideas?

Best wishes,

Chantel Davies
