dc.description.abstract [EN] Reconstruction of monuments often raises the question of stones replacement. It must be aesthetically durable, which means the stone must age like the original one. This study presents an image processing chain, from capture to visualisation, to compare stones at different states of aging: recently extracted from quarry, weathered on old buildings, and cleaned on monuments recently restored. This tool includes: (1) a digital still camera calibration, (2) a chromatic adaptation transform and (3) a resizing process. To test it, a case study was conducted to assess the compatibility of three types of limestone. This graphical tool helps the selection of replacement materials by visual comparison between several possible stones in order to select them by aging properties and visual resemblance. es_ES
dc.description.abstract [ES] En el ámbito de la sustitución de piedras en los monumentos, frecuentemente se plantea el problema de la selección de las piedras de reemplazo. De hecho, la reconstrucción debe ser estéticamente duradera, es decir, la piedra sustituida debe envejecer como la piedra original. Este estudio presenta una cadena de procesamiento de imágenes, desde la adquisición hasta la visualización, que permite comparar imágenes de piedras en varias etapas de su envejecimiento: recién extraída de la cantera, envejecida en edificios antiguos, y decapada con arena en monumentos recién restaurados. Esta herramienta incluye: (1) una calibración de cámara digital, (2) una transformación de adaptación cromática y (3) una etapa de redimensión. Para testear el método propuesto, un estudio de caso se llevó a cabo para evaluar la compatibilidad de tres tipos de caliza. Esta herramienta gráfica puede ayudar la selección de materiales de reemplazo con envejecimiento complejo como la piedra natural. es_ES
