Abstract

El uso de modelos paramétricos para capturar y representar la geometría de señal local permite un nuevo esquema de intra-predicción geométrica para codificar mejor las imágenes de video. El esquema de codificación ofrece al codificador de video la flexibilidad y escalabilidad para hacer coincidir el contenido de cuadro de video con la complejidad computacional deseada. Esto permite al codificador codificar las imágenes en forma más eficiente con el uso de la intra-predicción ya que reduce los bordes artificiales durante la intra-codificación normal.
