Tree ring analysis

Tree ring analysis provides useful data for dendrochnologists that can help them for better understanding of climatic and environmental changes. Yet detection and counting of rings in cross section of tree were realized manually which is time consuming and tedious work. Our research was motivated by the need of a fast and accurate method. This paper describes a semi automatic approach for tree rings detection and areas measurement based on 2D gray scale image analysis. Best results are obtained with the developed procedures. A newly algorithm well adapted for blurred and noisy image that smoothes it before detecting the boundaries with a 3^rd order recursive filter followed by edge extraction and 3D reconstruction of the tree
