In this article it is presented an analytical overview of original methods for increasing the contrast of joint distribution matrices using the demonstrative and exponential transformations of their energy density in a frequency-time space. We see the examples of modelling, which define the focus of developed approaches. We are given the practical recommendations how to use them.
