Title (EN) IMAGE ENCODING/DECODING METHOD AND APPARATUS USING INTRA-SCREEN PREDICTION
(FR) PROCÉDÉ ET APPAREIL DE CODAGE/DÉCODAGE D'IMAGE UTILISANT UNE PRÉDICTION INTRA-ÉCRAN
(KO) 화면 내 예측을 이용한 영상 부호화/복호화 방법 및 장치
Abstract: front page image
(EN)Disclosed is a decoding method which uses an intra-screen prediction. A decoding method which uses an intra-picture prediction performed in a decoding apparatus comprises the steps of: receiving a bit stream; obtaining decoding information from the received bit stream; generating a prediction block for a current block to be decoded using the obtained decoding information; and restoring the current block by adding a residual block obtained from the bit stream and the prediction block. Accordingly, a compression ratio of an image can be improved.
(FR)L'invention concerne un procédé de décodage qui utilise une prédiction intra-écran. L’invention concerne un procédé de décodage qui utilise une prédiction intra-image réalisée dans un appareil de décodage, ledit procédé consistant à : recevoir un train binaire ; obtenir des informations de décodage à partir du train binaire reçu ; générer un bloc de prédiction pour un bloc actuel devant être décodé à l'aide des informations de décodage obtenues ; et restaurer le bloc actuel en ajoutant un bloc résiduel obtenu à partir du train binaire et du bloc de prédiction. Par conséquent, il est possible d'améliorer un taux de compression d'une image.
(KO)화면 내 예측을 이용한 복호화 방법이 개시된다. 복호화 장치에서 수행되는 화면 내 예측을 이용한 복호화 방법은, 비트 스트림을 수신하는 단계, 수신된 비트 스트림에서 복호화 정보를 획득하는 단계, 획득한 복호화 정보를 이용하여 복호화하려는 현재 블록에 대한 예측 블록을 생성하는 단계 및 비트 스트림에서 획득된 잔차 블록과 예측 블록을 가산하여 현재 블록을 복원하는 단계를 포함할 수 있다. 따라서, 영상의 압축률이 향상될 수 있다.
