Equations of Nonlinear Analogue Circuit for Fault Dictionary Generation

not heavy for windows which are not too large, such as those that should be used for segmentation purposes. Moreover, two points should be noted. First, for the parameters of the form ^g(\i—j\ )ps(i, j), the co-occurrence matrix need not be stored; in fact, in eqn. 1 the elements Ms(i, j) do not appear. Secondly, the number of grey levels K does not influence the computational complexity of the parameters. However, an initialisation of the parameters must be done for the left-most window of each row. Indicating by £„, the summation over all pairs in the window w(m, n), we can calculate parameters of the form £ g( 11 — j\ )ps(i, j) with
