Abstract

Эффективное предсказание выборок в блоке в кодере и декодере видео посредством вычисления как интер-предсказанной гипотезы предсказания, так и интра-предсказанной гипотезы предсказания. Две гипотезы предсказания затем комбинируются вместе посредством параметрического преобразования для формирования новой гипотезы предсказания, которая может быть более точной в предсказании содержимого исходного блока.
