Error Model in Wavelet-compressed Images

This article presents the compression of images through the comparison between the Wavelet model and the Fourier model, using the minimization of the error function. The problem studied is specific, it consists in determining a base {ei} that minimizes the error function between the original image a...

El problema que se estudia es específico, consiste en determinar una base {ei} que minimice la función de error entre la imagen original y la recuperada después de la compresión. Es de resaltar que existen muchas aplicaciones, por ejemplo, en medicina o astronomía, en donde no es aceptable ningún deterioro de la imagen porque toda la información contenida, incluso la que se estima como ruido, se considera imprescindible.application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/461http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/461Copyright (c) 2007 Jairo Villegas G., Gloria Puetamán G., Hernán Salazar E.Acceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 3, No 5 (2007)Error Model in Wavelet-compressed ImagesModelo de error en imágenes comprimidas con waveletsarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1WaveletImage CompressionObserved ImageLinear And Nonlinear CompressionWaveletCompresión De ImágenesImagen ObservadaCompresión Lineal Y No LinealVillegas Gutiérrez, Jairo AlbertoPuetamán G., GloriaSalazar E., HernánUniversidad EAFITUniversidad de San BuenaventuraUniversidad de San BuenaventuraIngeniería y Ciencia35111133ing.cienc.THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/b6ae76bb-9648-4956-bfd3-a0f9af3f8e30/downloadda9b21a5c7e00c7f1127cef8e97035e0MD51ORIGINALdocument (3).pdfdocument (3).pdfTexto completo PDFapplication/pdf252691https://repository.eafit.edu.co/bitstreams/e7f367c4-0fb3-48f2-9e9b-af64eeaf704a/download8daba207bc05494d9838e95f0e9962c7MD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html373https://repository.eafit.edu.co/bitstreams/ced10c39-1cb1-4d28-b817-ea602db2e962/downloade77be572142c233094c2dd6a67bf5b53MD5310784/14546oai:repository.eafit.edu.co:10784/145462020-03-02 23:24:43.479open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co
