intra coding

高效率視訊編碼(HEVC)中的幀內編碼(英语:Intra Coding,又稱畫面內編碼)可以視為高階視訊編碼(Advanced Video Coding,H.264/AVC)的擴展,因為他們都是利用空間上的取樣預測來編碼,而高效率視訊編碼的幀內編碼包含以下基本元素:. 基於四元樹(Quadtree)編碼結構; 有33種預測方向的角度預測(Angular Prediction); 藉由 ... ,所謂Intra coding是將MB 經過離散餘弦轉換(DCT)、量化和可變. 長度編碼處理完成編碼。解碼的原理和編碼相類似,只是程序相. 反,直接做可變長度解碼(Variable Length Decoding, VLD)、反量化. 和離散餘弦反轉換(Inverse DCT, IDCT)的處理。這種大區塊的編碼. 方式就稱作Intra mode。Intra mode 主要是利用離散餘弦轉換的特性來. ,Intra-frame coding is used in video coding (compression).
