Agaian, S.S., Panetta, K., & Grigoryan, A.M. Keywords: Morphological contrast, opening by reconstruction, contrast index, Weber's law.ġ. The performance of our proposal is illustrated with a set of images processed by contrast mapping and compared with two contrast measures given in the literature. The index is based on Weber's law and takes into account background estimation through the erosion of opening by reconstruction. In this work, a contrast index for quantifying the perceived contrast in an image is proposed. Palabras clave: Contraste morfológico, apertura por reconstrucción, índice de contraste, ley de Weber. El desempeño de la propuesta se ilustra con un conjunto de imágenes procesadas por un mapeo de contraste y se compara con dos medidas de contraste dadas en la literatura. El índice está basado en la ley de Weber y toma en consideración una estimación del fondo de la imagen mediante la erosión de la apertura por reconstrucción. 76240, Querétaro, México.Įn este artículo se presenta un índice para cuantificar el contraste que se percibe en una imagen.
