Frequency is treated as a function of a normally distributed, random crystal angle and a deterministic temperature. Four different means of specifying the FTC and the resulting PDFs are presented.

The proposed method is based on matrix representation of the composites (FP) systems using the basis matrix and the block basis matrix which are extensions of the basis function. We propose a procedure to derive the basis matrix for composite FP systems from any grayscale structuring element (GSE). It is shown that opening, closing, clos-opening (CO) and open-closing (OC) are accomplished by local matrix operations rather than cascade operations and thus eliminating delays and requiring less memory storage
