ABSTRACT

Wood based structures are commonly used in many industries including oil and gas industry. It is very important to know the strength of the wood used in these structures. The strength of wood depends on the internal structure of fibres and orientation of knots. It is important to find the exact orientation of knots and fibres present in wood sample. The detection of ring present in Rosewood plays a vital role in consideration of strength of wood for different applications. The present work encompasses a micro level reconstruction of Rosewood by using micro X-rays CT scanner. The proposed approach is based on the newly designed fractional order mask. The mask has been designed by Chebyshev polynomial based approximation. The Riemann-Liouville (RL) definition of fractional derivative has been used for calculation of fractional order mask. Pre-processing algorithm has been performed with the proposed mask. The algorithm has been tested on Rosewood images. The effect of relaxation coefficient has also been discussed in present work. The effect of size of mask has also been highlighted.
