Comparison of Image Compressions: Analog Transformations
Proceedings, 2020 A comparison between the four most used transforms, the discrete Fourier transform (DFT), discrete cosine transform (DCT), the Walsh–Hadamard transform (WHT) and the Haar-wavelet transform (DWT), for the transmission of analog images, varying their ...

Compressive Optical Spectrometry Based on Sequency-Ordered Hadamard Transform
IEEE Photonics Journal, 2020 We propose a compressive Hadamard transform spectrometer (CHTS) based on the energy compaction trait of the sequency-ordered Hadamard matrix (SOHM), in which the spectrum is reconstructed from compressed measurements using simple matrix multiplication ...

Characterization of Basic 5-Value Spectrum Functions Through Walsh-Hadamard Transform
IEEE Transactions on Information Theory, 2021 The first and the third authors recently introduced a spectral construction of plateaued and of 5-value spectrum functions. In particular, the design of the latter class requires a specification of integers $\{W(u):u\in \mathbb {F}^{n}_{2}\}$ , where ...
