Computation of the Wigner distribution function by the Hartley transform. Application to image restoration

AbstractUsually a Fast Fourier Transform algorithm (FFT) is applied to calculate the Discrete Wigner Distribution Function (DWDF). In this paper it is proposed to use the Discrete Hartley Transform (DHT) to obtain the DWDF, because of the advantages of the Fast Hartley Transform algorithm versus the FFT. The Hartley Transform not only decreases the computer time of the WDF but also simplifies the convolution of two WDFs. This fact is used here to simulate a blurred image and its restoration. © 1988.
