Due to the large amount of information present in the form of images or videos, compression of these data is necessary. Compressed sensing is an efficient technique to meet this challenge. It consists in acquiring a signal, assuming that it can have a sparse representation, by using a minimum number of nonadaptive linear measurements. After this compressed sensing process, a reconstruction of the original signal must be performed at the receiver. Reconstruction techniques are often unable to preserve the texture of the image and tend to smooth out its details. To overcome this problem, we propose, in this work, a compressed sensing reconstruction method that combines the total variation regularization and the non-local self-similarity constraint. The optimization of this method is performed by using an augmented Lagrangian that avoids the difficult problem of nonlinearity and nondifferentiability of the regularization terms. The proposed algorithm, called denoising-compressed sensing by regularization (DCSR) terms, will not only perform image reconstruction but also denoising. To evaluate the performance of the proposed algorithm, we compare its performance with state-of-the-art methods, such as Nesterov\u2019s algorithm, group-based sparse representation and wavelet-based methods, in terms of denoising and preservation of edges, texture and image details, as well as from the point of view of computational complexity. Our approach permits a gain up to 25% in terms of denoising efficiency and visual quality using two metrics: peak signal-to-noise ratio (PSNR) and structural similarity (SSIM).<\/jats:p>","DOI":"10.3390\/s22062199","type":"journal-article","created":{"date-parts":[[2022,3,13]],"date-time":"2022-03-13T21:44:17Z","timestamp":1647207857000},"page":"2199","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":94,"title":["Image Denoising Using a Compressive Sensing Approach Based on Regularization Constraints"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1249-4541","authenticated-orcid":false,"given":"Assia El","family":"Mahdaoui","sequence":"first","affiliation":[{"name":"AMNEDP Laboratory, Department of Analysis, University of Sciences and Technology Houari Boumediene, Algiers 16111, Algeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6392-7693","authenticated-orcid":false,"given":"Abdeldjalil","family":"Ouahabi","sequence":"additional","affiliation":[{"name":"UMR 1253, iBrain, INSERM, Universit\u00e9 de Tours, 37000 Tours, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed Said","family":"Moulay","sequence":"additional","affiliation":[{"name":"AMNEDP Laboratory, Department of Analysis, University of Sciences and Technology Houari Boumediene, Algiers 16111, Algeria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1049\/iet-ipr.2018.5173","article-title":"Fast and accurate compressed sensing model in magnetic resonance imaging with median filter and split Bregman method","volume":"13","author":"Yang","year":"2019","journal-title":"IET Image Process."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"292","DOI":"10.1016\/S0041-624X(99)00113-4","article-title":"Harmonic propagation of finite amplitude sound beams: Experimental determination of the nonlinearity parameter B\/A","volume":"38","author":"Labat","year":"2000","journal-title":"Ultrasonics"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"2417","DOI":"10.1109\/LCOMM.2019.2941194","article-title":"Compressive multi-attribute data gathering using hankel matrix in wireless sensor networks","volume":"23","author":"He","year":"2019","journal-title":"IEEE Commun.
