Abstract

Se proporciona un método para interpolar imágenes al determinar un coeficiente de filtro de interpolación. Se describe un método de interpolación de imagen que toma en cuenta alisado para generar el valor de píxel de al menos una unidad al sub-píxel, en ese método: se selecciona un filtro de interpolación de entre filtro se interpolación para generar el o los valores de píxel de al menos una unidad de sub-píxel colocada entre unidades de píxel, la selección se realiza en una forma que difiere con base en la posición de interpolación y la homogeneidad de la o las unidades de sub-píxel; y el filtro de interpolación seleccionado se utiliza con el fin interpolar valores de píxel de píxeles de unidad de pixel.
