Abstract

Se describe un método para interpolación de subpixel para una imagen que utiliza un filtro de interpolación con base en conversión, el método para interpolación de imagen comprende: seleccionar, para cada punto de interpolación de nivel de sub-pixel, un filtro de interpolación simétrico o un filtro de interpolación asimétrico de entre filtros de interpolación con respecto a un punto de interpolación, en donde los filtros de interpolación son para generar el valor de pixel de al menos un sub-pixel que está colocado entre los pixeles; y generar el valor de pixel de al menos un sub-pixel al interpolar de los valores de pixel de pixeles utilizando el filtro de interpolación seleccionado.
