Mejora de Contraste y Compensación en Cambios de la Iluminación

In this paper a contrast operator built by means of two primitives involving Weber’s Law is presented. The proposed contrast mapping has two objectives, in the first place the contrast enhancement and in the second, the normalization of the processed image. The contrast enhancement is based on the image background detection; this parameter is computed through the analysis of the regional minimu...

Cambios Rpidos en las Directrices en Comunidades de Pescadores de Yangtze y en la Memoria Local de Especies Extintas

Local ecological knowledge can provide a unique source of data for conservation, especially in efforts to investigate the status of rare or possibly extinct species, but it is unlikely to remain constant over time. Loss of perspective about past ecological conditions caused by lack of communication between generations may create “shifting baseline syndrome,” in which younger generations are les...

Modelado de Cambios de Nivel en Series de Tiempo No Lineales Usando Redes Neuronales Artificiales

It is usually accepted that many physical and economical variables shown nonlinear dynamical behaviors which complexity makes it impossible to formulate an econometric model based only on physical or economic laws that properly represents its evolution. The formulation of model is aggravated with the presence of outliers and structural breaks, for which there are not any mathematical models tha...
