Abstract
The goal of this paper is to document the use of time series in color matching. Although time series are not commonly used for this purpose, the results obtained, based on the principle of similarity in time series using the Euclidean distance, establish the validity of its use for color matching applications. The accuracy of color matching was based on the measures of reflectivity versus wavelength of samples given by a spectrophotometer. The error estimation was calculated using a database of 1001 elements. The matching module has been tested with six samples included and not included in the database. All of them gave an error lower than the estimated absolute error of 11.36.
Keywords: Time series; Color matching; Pattern recognition; Similarity; Color management systems.
Resumen
El propósito de este trabajo es documentar el uso de las series de tiempo en el pareo de colores. Aunque las series de tiempo no son usadas comúnmente con este fin, los resultados obtenidos, basados en el principio de similitud en las series de tiempo mediante la distancia euclidiana, establece la validez de su uso en las aplicaciones de pareo de colores. La exactitud del pareo de colores se basó en las medidas de la reflectividad contra la longitud de onda de las muestras, dadas por un espectro fotómetro. La estimación del error fue calculada a partir de una base de datos de 1001 elementos. El módulo de pareo ha sido probado con seis muestras incluidas y no incluidas en la base de datos. Todas ellas dieron un error menor que el error absoluto estimado de 11.36.
Palabras clave: Series de tiempo; Pareo de colores; Reconocimiento de patrones; Similitud; Sistemas de administración del color.
