Shared Congestion Detection: A Comparative Study
Journal of Engineering, 2023 Most Internet-tomography problems such as shared congestion detection depend on network measurements. Usually, such measurements are carried out in multiple locations inside the network and relied on local clocks.

COMPARISON COMPRESSION PROPERTIES DWT WITH FB 5/3 AND FB 9/7 [PDF]
Acta Electrotechnica et Informatica, 2019 The suitability of 2-dimensional Discrete Wavelet Transform (2D DWT) as a tool in image and video compression is nowadays indisputable. Wavelet based techniques such as JPEG2000 for image compression has a lot more to offer than conventional methods in

Image Watermarking Using 3-Level Discrete Wavelet Transform (DWT) [PDF]
International Journal of Modern Education and Computer Science, 2012 We have implemented a robust image watermarking technique for the copyright protection based on 3-level discrete wavelet transform (DWT). In this technique a multi-bit watermark is embedded into the low frequency sub-band of a cover image by using alpha blending technique.

Per-Wavelet Equalization for Discrete Wavelet Transform Based Multi-Carrier Modulation Systems
IEEE Open Journal of Signal Processing, 2023 The Discrete Wavelet Transform (DWT) has gained attention in the area of Multi-Carrier Modulation (MCM) because it can overcome some well known limitations of Discrete Fourier Transform (DFT) based MCM systems.

Comments on "phase-shifting for nonseparable 2-D haar wavelets" [PDF]
, 2009 In their recent paper, Alnasser and Foroosh derive a wavelet-domain (in-band) method for phase-shifting of 2-D "nonseparable" Haar transform coefficients. Their approach is parametrical to the (a priori known) image translation.

On the application of wavelet transform and Huffman algorithm to Yorùbá language syntax text files compression [PDF]
Serbian Journal of Electrical Engineering, 2022 Most algorithms of data compression were developed with English language as target text syntax. However, this paper approaches the problem of Yorùbá text files compression via the use of Discrete Wavelet Transform (DWT) and Huffman algorithm ...

On the energy leakage of discrete wavelet transform [PDF]
, 2008 The energy leakage is an inherent deficiency of discrete wavelet transform (DWT) which is often ignored by researchers and practitioners. In this paper, a systematic investigation into the energy leakage is reported.
