This paper describes a method of enhancement of grayscale and color image in the
frequency domain by the pair of two elliptic discrete Fourier transforms (EDFT). Unlike the …

ABSTRACT A parallel restoration procedure obtained through a splitting of the signal into
multiple signals by the paired transform is described. The set of frequency-points is divided …

In this paper is described a method for automatic analysis of missing block neighbor area.
The analysis, which is based on Canny edge detection and calculation of homogeneity …

Tomographic imaging is an important tool which is used in cancer to detect tumors and
provide information about the extent of disease, help plan treatment, and determine whether …

This paper describes a new solution of the problem of two-dimensional (2-D) image f (x, y)
reconstruction from a finite number of line-integrals. The reconstruction is a discrete image f …

In this paper, we present a novel concept of the quaternion discrete Fourier transform on the
two-dimensional hexagonal lattice, which we call the two-dimensional hexagonal …
