Abstract

Se proporciona un codificador de imágenes, el cual incluye circuitería y una memoria acoplada a la circuitería. La circuitería, en operación, realiza una operación de sintaxis de partición que incluye: dividir un bloque de imagen en una pluralidad de particiones que incluyen una primera partición que tiene una forma no rectangular (por ejemplo, una forma triangular) y una segunda partición con base en un parámetro de partición que es indicativo de la división; codificar la primera partición y la segunda partición; y escribir uno o más de los parámetros que incluyen el parámetro de partición en una corriente de bits.
