In this paper, we propose a new method for the rapid calculation of Meixner’s discrete orthogonal moments and its inverses. In this method, we have used the notion of digital filters based on the Z transform both to accelerate the computation time of Meixner and to reduce the reconstruction error of the images. To guarantee the numerical stability and(More)
In this paper, we will present a new method of image reconstruction using a new type of separable discrete orthogonal moments called the Krawtchouk-Tchebichef moments. The latter are based on the bivariate discrete orthogonal polynomials defined from the product of Krawtchouk and Tchebichef of discrete orthogonal polynomials with a variable. The new method(More)
In this paper we introduce a method for fast computation of Krawtchouk moments by using of cascaded digital filters. The proposed method based on the outputs of cascaded digital filters operating as accumulators are combined with a simplified Krawtchouk polynomials to form Krawtchouk moments depends on the formulation of Krawtchouk polynomials in terms of(More)
