L'analyse des coefficients de transformée quantifiée est un outil important pour le codage vidéo. Par exemple, le codeur vidéo MPEG-4 adopte trois analyses différentes pour obtenir une meilleure efficacité de codage. Cet article propose une analyse de distribution adaptative à coefficient zéro dans le codage inter-blocs. La méthode proposée tente d'améliorer le codage à coefficient zéro H.264/AVC en modifiant l'opération de balayage. Étant donné que la distribution à coefficient zéro est modifiée par la méthode de balayage proposée, de nouvelles tables VLC pour les éléments de syntaxe utilisés dans le codage à longueur variable adaptatif au contexte (CAVLC) sont également fournies. Les économies de débit varient de 2.2 % à 5.1 % dans les cas de débit binaire élevé, en fonction des différentes séquences de test.

Abstract: Scanning quantized transform coefficients is an important tool for video coding. For example, the MPEG-4 video coder adopts three different scans to get better coding efficiency. This paper proposes an adaptive zero-coefficient distribution scan in inter block coding. The proposed method attempts to improve H.264/AVC zero coefficient coding by modifying the scan operation. Since the zero-coefficient distribution is changed by the proposed scan method, new VLC tables for syntax elements used in context-adaptive variable length coding (CAVLC) are also provided. The savings in bit-rate range from 2.2% to 5.1% in the high bit-rate cases, depending on different test sequences.
