چکیده
Discrete analogs of the Lebedev–Skalskaya transforms are introduced and investigated. It involves series integrals with respect to kernels Re Kα+in(x),Im Kα+in(x),x>0,n∈N,|α|<1, i is imaginary unit Kν(z) modified Bessel function. The corresponding inversion formulas for suitable functions sequences in terms these established when α=±1/2. case α=0 reduces Kontorovich–Lebedev transform.

Sliding discrete fractional transforms
Fractional transforms are useful tools for processing of non-stationary signals. The methods of implementing sliding discrete fractional Fourier transform (SDFRFT), sliding discrete fractional cosine transform (SDFRCT) and sliding discrete fractional sine transform (SDFRST) for real time processing of signals are presented. The performances of these sliding transforms, with regard to computatio...
متن کاملFast Discrete Curvelet Transforms
This paper describes two digital implementations of a new mathematical transform, namely, the second generation curvelet transform [12, 10] in two and three dimensions. The first digital transformation is based on unequally-spaced fast Fourier transforms (USFFT) while the second is based on the wrapping of specially selected Fourier samples. The two implementations essentially differ by the cho...
متن کاملDiscrete Affine Wavelet Transforms
In this paper we show that discrete affine wavelet transforms can provide a tool for the analysis and synthesis of standard feedforward neural networks. It is shown that wavelet frames for L2(IR) can be constructed based upon sigmoids. The spatia-spectral localization property of wavelets can be exploited in defining the topology and determining the weights of a feedforward network. Training a ...

متن کاملComparison of Discrete Cosine Transforms (DCT), Discrete Fourier Transforms (DFT), and Discrete Wavelet Transforms (DWT) in Digital Image Watermarking
Digital Image Watermarking is used recently to secure the image by embedding another digital image. It is typically used to identify ownership of the copyright of the signal. Frequency domain transformation methods used widely in Digital Image Compression and Digital Image Watermarking. They reduce the weakness of classics digital image watermarking such as Least Significant Bit (LSB) methods w...
