Weigert Method

The Weigert method (German: Veigertscher methode), also called the frequency space method, or spatial frequency technique (English: Spatial frequency/Spatio-frequency technique) is an image processing method that characterizes the distribution of local image quality by its frequency. The name of the method is given in honor of Rainer Weigers (until 1975 René Weigers), German. Feigertcher. Frequency analysis is directly related to the theory of basis functions. Weigert (1964) posed the problem of Fourier transforming texture as a two-dimensional distribution of amplitudes of related components of the frequency spectrum, which did not lose a single pixel and did not create distortions. This process has received
