Mainly because there are ample causes for the strength degeneration of components, coupled with the change of physical properties of the material itself, it is hard to show the non-stationary stochastic process of strength degeneration by a certain mathematical model.

Kerlman and Thomas A[8], although the PWM literature is rich and the technology is mature, the educational material in this field is scare, and since the modulator characteristics are often complex, multivariable functions and the analytical formulas are nonintuitive, the PWM learning process can be discouraging, and a methodical approach is required.

Due to its ubiquity it is often called the k-means algorithm; it is also referred to as Lloyd's algorithm, particularly in the computer science community.
The result of the transform is a graylevel image that looks similar to the input image, except that the graylevel intensities of points inside foreground regions are changed to show the distance to the closest boundary from each point.One way to think about the distance transform is to first imagine that foreground regions in the input binary image are made of some uniform slow burning inflammable material.
