Abstract

Procedimiento para la generación de una imagen bidimensional a partir de un juego de datos bidimensionales de partida, que define una distribución de valores de color o de gris, en el que: a) las posiciones de apoyo del juego de datos de partida son puntos de vértice de rectángulos, que se dividen en triángulos; b) se asignan valores de color o de gris a la región interior de los triángulos mediante interpolación de los valores de color o de gris en los puntos de vértice de los triángulos, para generar un modelo continuo de datos; c) mediante el desplazamiento de los puntos de vértice se reducen o minimizan las curvaturas de la superficie definida por la distribución de valores de gris o de color, con lo que el modelo continuo de datos se desplaza correspondientemente; y d) se genera una imagen bidimensional a partir del modelo continuo de datos desplazado; en el que e) para la determinación de la curvatura se emplea la superficie de la proyección de un triángulo en la dirección del gradiente.
