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 ...

Discrete cosine transform based de-noising of glottal pulses
Archives of Acoustics, 2004 Reliable estimates of the glottal function are of major importance in speech/voice processing for the characterization of voicing conditions, description of various phonation types, and identification of their parameters.

Text-image watermarking based on integer wavelet transform (IWT) and discrete cosine transform (DCT)
Applied Computing and Informatics, 2019 Text-images still have a great importance, despite the spread of electronic texts. Text-images are protected using digital watermarking. This paper proposes a watermarking method applied to text-images.

CORRELATION ANALYSIS OF DISCRETE COSINE TRANSFORM COEFFICIENTS OF IMAGE BLOCKS
Радіоелектронні і комп'ютерні системи, 2016 Task of lossy image compression based on discrete cosine transform (DCT) is considered. For image blocks having size 8x8 pixels (it corresponds to division of images on blocks in JPEG standard) presence of correlation between different DCT coefficients ...
