There are many situations in which linear filters perform poorly, as in the presence of signal-dependent or multiplicative noises or processing of signals having non-Gaussian statistics. In these cases it is evident to apply nonlinear filters. The author focuses on the mathematical models of nonlinear filters and their application fields. The example of(More)
119 Toaddheaded agamas (Phrynocephalus) is an essenn tial element of arid biotopes throughout the vast area spanning the countries of Middle East and Central Asia. They constitute one of the most diverse genera of the agama family (Agamidae), variously estimated to comprise 26 to 40 species [1]. The subgeneric Phrynoo cephalus taxonomy is poorly studied:(More)
