Because of the inherent physical difficulties of various recording technologies, images are prone to the emergence of some noise during image acquisition. In the existing methods, poor illumination and atmospheric conditions affect the overall performance. To solve these issues, in this paper Political Taylor-Anti Coronavirus Optimization (Political Taylor-ACVO) algorithm is developed by integrating the features of Political Optimizer (PO) with Taylor series and Anti Coronavirus Optimization (ACVO). The input medical image is subjected to noisy pixel identification step, in which the deep residual network (DRN) is used to discover noise values and then pixel restoration process is performed by the created Political Taylor-ACVO algorithm. Thereafter image enhancement mechanism strategy is done using vectorial total variation (VTV) norm. On the other hand, original image is applied to discrete wavelet transform (DWT) such that transformed result is fed to non-local means (NLM) filter. An inverse discrete wavelet transform (IDWT) is utilized to the filtered outcome for generating the denoised image. Finally, image enhancement result is fused with denoised image computed through filtering model to compute fused output image. The proposed model observed the value for Peak signal-to-noise ratio (PSNR) of 29.167 dB, Second Derivative like Measure of Enhancement (SDME) of 41.02 dB, and Structural Similarity Index (SSIM) of 0.880 for Gaussian noise.<\/jats:p>","DOI":"10.1142\/s021946782550072x","type":"journal-article","created":{"date-parts":[[2024,3,21]],"date-time":"2024-03-21T04:01:31Z","timestamp":1710993691000},"source":"Crossref","is-referenced-by-count":2,"title":["Deep Residual Network and Wavelet Transform-Based Non-Local Means Filter for Denoising Low-Dose Computed Tomography"],"prefix":"10.1142","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1429-9264","authenticated-orcid":false,"given":"Rashmita","family":"Sehgal","sequence":"first","affiliation":[{"name":"Department of Computer Science, Harcourt Butler Technical University, Nawabganj, Uttar Pradesh, Kanpur 208002, India"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0394-263X","authenticated-orcid":false,"given":"Dr. Vandana Dixit","family":"Kaushik","sequence":"additional","affiliation":[{"name":"Department of Computer Science, Harcourt Butler Technical University, Nawabganj, Uttar Pradesh, Kanpur 208002, India"}]}],"member":"219","published-online":{"date-parts":[[2024,3,20]]},"reference":[{"key":"S021946782550072XBIB001","first-page":"1","volume":"16","author":"Priya S.","year":"2021","journal-title":"Signal Image Video Process."},{"issue":"4","key":"S021946782550072XBIB002","first-page":"683","volume":"34","author":"Cho T.
