Example of L S input image. An example of L S image used later to demonstrate the next operation steps of algorithm calculating the value of coefficient w(2). The interpretation of brightness levels is not required here. In the image there are three isolated areas that contain the values 1, 2 and 9. They are an isolated focus. The surrounding pixel values equal to 40 are the backdrop. In the next step of the algorithm, those focuses (1, 2 and 9) are automatically separated from the backdrop (the values of 40). The number of pixels in the focus is not significant here. What matters are their surroundings - in this case the values of 40.
