Abstract

MÉTODO DE CODIFICAÇÃO DE VÍDEO COM O USO DE PARTICIONAMENTO DE BLOCO DE ÁRVORE BINÁRIA. Trata-se de um método para codificar vídeo com o uso de processo de particionamento de bloco que inclui um processo de particionamento de árvore binária. O processo de particionamento de bloco é aplicado a um bloco de dados de vídeo para particionar o bloco em sub-blocos finais. O processo de codificação compreende processo de predição, processo de transformação ou ambos para o bloco serão aplicados ao nível de sub-blocos finais. O processo de particionamento de árvore binária pode ser aplicado a um determinado bloco de modo recursivo para gerar nós de folha de árvore binária até que uma condição de terminação seja alcançada. Em outra modalidade, o processo de particionamento de quadtree é aplicado a um bloco primeiro. Os nós de folha de quadtree são ainda particionados com o uso do processo de particionamento de árvore binária. O processo de particionamento de quadtree pode ser aplicado a um determinado bloco de modo recursivo para gerar nós de folha de quadtree até que uma condição de terminação seja alcançada.
