Algorithms to estimating fractal dimension of textured images

Two algorithms that can obtain more accurate estimate of the fractal dimension are proposed. One is the shifting DBC (SDBC) algorithm and the other one is the scanning BC (SBC) algorithm. It is theoretically proven that the SDBC algorithm approaches the estimated value closer to the exact fractal dimension than the DBC method. Simulation results show that the proposed algorithms consistently give more satisfactory results on textured images.
