Abstract

MÉTODO E APARELHO DE INTRAPREDIÇÃO NÃO QUADRADA PARA COMPONENTES CROMA EM SISTEMA DE CODIFICAÇÃO COM PARTIÇÃO DE ÁRVORE QUATERNÁRIA E ÁRVORE BINÁRIA. Trata-se de um método e aparelho para intrapredição de blocos croma não quadrados. O sistema usa uma estrutura de particionamento de bloco para particionar um bloco croma em um ou mais sub-blocos finais que incluem pelo menos um subbloco final não quadrado com o uso de partição de bloco recursivamente. A partição de bloco tanto divide cada dado bloco em sub-blocos intermediários com o uso de um ou mais modos de divisão que incluem um modo de divisão binária como não aplica nenhuma divisão a cada dado bloco. O bloco é tratado como um dado bloco inicial e cada sub-bloco intermediário é tratado como um dado bloco em uma próxima recursão. Qualquer dado bloco que não é dividido adicionalmente se torna a sub-bloco final. Após os sub-blocos finais serem determinados, a intrapredição não quadrada é aplicada a cada sub-bloco final não quadrado.
