摘要：In this paper, based on the relationship between the X-ray energy attenuation and the scanning object density, the weighted filtered back projected algorithm is proposed to satisfy the compelling different density of multi-species stumpage. In order to verify the effectiveness of the proposed algorithm, filtered back projection algorithm and some applied hybrid filter functions are described in detail. Using the scanning data of pine logs, numerical simulations are completed by utilizing RL-SL filtered and RL-Ramp filtered and weighted filtered methods respectively. The effectiveness and applicability of the weighted filtered back projected algorithm is verified intuitively by the results of both the reconstruction images and the error statistics data.
