Abstract : In this study, the detection and counting of annual rings were determined by signal processing methods. The surface density graph of the annual ring image was plotted and a signal was obtained. Since the signal contains noise, 1-D filtering processing was applied to the signal. This minimizes the noise and regions that cannot be annual rings. The annual ring numbers and width were determined with a threshold value calculated from the surface graph obtained from the image. Matlab program was used for these operations. The number of annual rings was determined quickly and easily.
