Abstract

La presente divulgación proporciona aparatos y métodos para dividir una imagen en unidades de codificación; una imagen es dividida en unidades de árbol de codificación (CTUs) las cuales son jerárquicamente divididas; la división jerárquica incluye división multi-tipo tal como división de árbol binario o árbol cuaternario; para CTUs completamente dentro de la imagen y CTUs en el límite, se eligen profundidades de división multi-tipo respectivas. La presente divulgación proporciona una flexibilidad de división multi-tipo en una porción delimitante de la imagen.
