適応ループ・フィルタリングにおける分類
Document Type and Number:
Japanese Patent JP2022541032
Kind Code:
A
Abstract:
ビデオ処理のための方法が、ビデオにおけるビデオ・ピクチャーのあるブロックとそのビデオのビットストリーム表現との間の変換のために、ある領域におけるサンプルの部分集合の勾配を、フィルタリング・プロセスにおける分類動作のために決定することを含む。前記領域はM×Nの寸法をもち、前記ブロックはK×Lの寸法をもち、M、N、K、Lは正の整数である。前記ブロックは前記領域内に位置する。本方法は、前記決定に基づいて前記変換を実行することをも含む。
