Abstract Dendrochronology is the science that dates wooden artefacts by measuring annual growth rings visible in wood. And, case of musical instruments, method non-invasive. In addition, dendrochronology can also help to identify wood’s provenance and supply information on how soundboard was made, giving details ring width regularity. This study demonstrates effectiveness attributing a instrume...

To help understand the effect of short term climatic changes on ring width variations of trees on Long Island, time series were performed on 6 Liriondendrin tuliperfera (tulip poplars) and 1 white oak from Caumsett State Park, and 6 Pinus rigidas (pitch pines) from Sears Bellows and Hubbard County Parks. Prolonged drought periods on Long Island occur during years 1927-1932, 1960-1970 and 1980-1...

The purpose of this paper is to describe the design and implementation of a computer vision based analysis system for dendrochronology. The issues involved in the detection and analysis of tree rings are not unique to the application, but are likely of interest to anyone developing automated image analysis systems.
