Thanks Hana, I downloaded imagej but I couldn't use it. it seems so complicated.
is this one easy or it needs experience?
I have images of dentine surface and I need the software to analyse it then I will compare the software analysis with manual analysis to check for correlation.
I would defintely recommend you visit www.MIPAR.us.
It is very powerful and intuitive 2D/3D image analysis software written by scientists/end-users and is about to be released as a free trial on December 14th. You can sign up on the site as well as submit images/datasets to test.
There are many image analysis options available, but I think you may just find MIPAR to be something special if you give it a try!
