An Introduction To Compressive Sampling [PDF]
IEEE Signal Processing Magazine, 2008 Conventional approaches to sampling signals or images follow Shannon's theorem: the sampling rate must be at least twice the maximum frequency present in the signal (Nyquist rate). In the field of data conversion, standard analog-to-digital converter (ADC) technology implements the usual quantized Shannon representation - the signal is uniformly ...

Vaguelette-Wavelet Deconvolution via Compressive Sampling
IEEE Access, 2019 Vaguelette-wavelet deconvolution (VWD) is known as a transform-based image restoration technique that involves applying wavelet-domain denoising to an observed image, followed by the Fourier-domain blur inversion, which can prevent noise amplification in
