Abstract
Se describen diferentes implementaciones, particularmente se presentan implementaciones para codificación y decodificación de video con base en un modelo lineal que responde a muestras vecinas. Por consiguiente, para un bloque que está siendo codificado o decodificado en una imagen, se determina al menos una plantilla vecina espacial y al menos un parámetro de modelo lineal con base en muestras reconstruidas de al menos una plantilla vecina espacial. En una primera modalidad, el número de N de muestras reconstruidas corresponde a N = 2k con k elegido de manera que n es el entero máximo más pequeño que la suma de la anchura del bloque y la altura del bloque. En una segunda modalidad, se determina un desfase para la posición relativa de una primera muestra en la plantilla entre muestras de una linea vecina izquierda, respectivamente superior del bloque. En una tercera modalidad, el número de muestras reconstruidas se establece a un número superior en la dimensión más grande del bloque.
