Cyclic Wiener Filtering Algorithm in Discrete Cosine Transform Domain for Vibration Signal
MATEC Web of Conferences, 2016 In order to solve the problem that the effect of using cyclic Wiener filter directly to remove the noise on the non-stationary vibration signal is poor, the paper applies discrete cosine transform to the cyclic Wiener filter, proposing the cyclic Wiener ...

The Discrete Cosine Transform on Triangles [PDF]
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019 The discrete cosine transform is a valuable tool in analysis of data on undirected rectangular grids, like images. In this paper it is shown how one can define an analogue of the discrete cosine transform on triangles. This is done by combining algebraic signal processing theory with a specific kind of multivariate Chebyshev polynomials.

Hybrid Algorithm Based on Hyper Spectral Noise Removal for Satellite Image
EAI Endorsed Transactions on Energy Web, 2020 Usually the image obtained from a sensor is blurred by noise. Such noises are identified and eliminated by the procedure called denoising. The cross breed (Hybrid) algorithm is a popular technique that has been utilized recently.

Image Hiding Using Discrete Cosine Transform
مجلة كلية التربية للبنات, 2019 Steganography is a mean of hiding information within a more obvious form of communication. It exploits the use of host data to hide a piece of information in such a way that it is imperceptible to human observer.

Comparison of discrete transforms for deep‐neural‐networks‐based speech enhancement
IET Signal Processing, 2022 In recent studies of speech enhancement, a deep‐learning model is trained to predict clean speech spectra from the known noisy spectra of speech. Rather than using the traditional discrete Fourier transform (DFT), this paper considers other well‐known ...
