Figure 4.

Example ofL_Smatrix. An example of L_S image used later to demonstrate the next operation steps of GLCM algorithm calculating the value of coefficient w(5). The interpretation of brightness levels is not required here. The next step will be the comparison of the neighborhood between horizontally neighbouring pixels. In this case there will be 16 neighborhoods. The value 16 results from four neighborhoods for each of 4 lines of the presented image (matrix). Among these 16 neighborhoods, there may appear both new neighborhoods as well as the previously detected ones.
