Abstract -
This paper describes a semi-automatic technique for dendroclimatology. Dating of tree rings and surveying the environmental changes by analysing the tree rings pattern in the cross section of tree image. Many algorithms are proposed, but still need sufficient improvement in this area. This paper describes a modified canny algorithm for detecting the edges and also proposed Hough transform technique for finding the annual period of trees and analysis the growth of tree which helps to get the environment changes in the particular area.
