Abstract

Un codificador incluye circuitos configurados para recibir un fotograma de vídeo, dividir el fotograma de vídeo en una pluralidad de bloques, determinar una medida de operación espacial en relación para cada bloque de la pluralidad de bloques y, utilizando una matriz de transformación, codificar el fotograma de vídeo utilizando la medida de operación espacial. También se describen aparatos, sistemas, técnicas y artículos relacionados.
