En el campo m\u00e9dico, muchos de estos t\u00e9rminos anteriores son medidos en t\u00e9rminos de m\u00fasculos, piel, \u00f3rganos, huesos y fluidos corporales. El problema viene que al usar rayos X, esc\u00e1neres y resonancias, estos dispositivos son muchas veces suficientes, pero otras el nivel de precisi\u00f3n requerido en el campo m\u00e9dico no es totalmente satisfecho. El VHDR, en concordancia con los \u00faltimos avances en medicina, tiene algo que aportar para mejorar dichas im\u00e1genes.<\/p>\n<figure id=\"attachment_7653\" aria-describedby=\"caption-attachment-7653\" style=\"width: 560px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/catai.net\/blog\/wp-content\/uploads\/2012\/10\/VHDR.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-7653\" title=\"VHDR\" src=\"https:\/\/catai.net\/blog\/wp-content\/uploads\/2012\/10\/VHDR.jpg\" alt=\"\" width=\"560\" height=\"217\" srcset=\"https:\/\/catai.net\/blog\/wp-content\/uploads\/2012\/10\/VHDR.jpg 560w, https:\/\/catai.net\/blog\/wp-content\/uploads\/2012\/10\/VHDR-300x116.jpg 300w\" sizes=\"auto, (max-width: 560px) 100vw, 560px\" \/><\/a><figcaption id=\"caption-attachment-7653\" class=\"wp-caption-text\">(Izquierda) Imagen de 8 bits original, (Derecha) imagen VHDR de 8 bits<\/figcaption><\/figure>\n<p>VHDR usa las disparidades en la imagen para resaltar los niveles bajos de contraste de un conjunto de datos que forman la imagen.
