Hi Hamid I recently published a paper with some colleagues on the issue of error assessment in geometric morphometrics:
The Problem of Assessing Landmark Error in Geometric Morphometrics: Theory, Methods, and Modifications American Journal of Physical Anthropology (in press) This might be of interest to you? It mainly deals with the problems of identifying landmarks on 3D objects when using a digitiser, so it may not be directly relevant to your problem but it does discuss the theoretical and practical problems surrounding landmark measurement error and the identification of poorly defined landmarks. I can send you a PDF of the paper should you wish. Good luck!
