“…Thus, estimation of fractal features requires a keen attention, so that accurate methods could be developed accordingly. Fractal dimension, the most popular fractal feature, can be estimated for digital images by considering the pixel values of predefined neighbourhoods as done in numerous available methods [1,3,[9][10][11][12][13][14][15][16], viz. differential box counting method [17], Triangular prism surface area method (TPSAM) [18,19], Fourier spectrum based method [2,3], Variogram method, Robust fractal dimension estimation [3], 2D variation method [20] which deal with image pixels and their orientation at a varying scale.…”
