Its advantages lie in the preservation of the image edges while the noise is removed, as opposed to the blurring that characterizes Butterworth filtered images. However, results show that total variation filtering application to SPECT medical images doesn’t represent an improvement in terms of similarity to the reference image5 p.application/pdfengcc-by-nc-nd (c) Ruiz, 2016http://creativecommons.org/licenses/by-nc-nd/3.0/es/Tomografia computada per emissió de fotó simpleTreballs de fi de grauSingle-photon emission computed tomographyBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
