    • Methods for fast mode decision of variable size block coding referring to spatial and temporal correlations between a current encoding motion block and at least one reference motion block to decide a best mode for encoding the current encoding motion block. The at least one reference motion block includes at least one neighboring motion block of the current motion block and/or a previous motion block that is located in a previous image frame at a position corresponding to that of the current encoding motion block in a current image frame. At least one block size mode is obtained from the at least one reference motion block. The methods further check the reliability of the at least one block size mode before using the at least one block size to encode the current motion block.
    • 参考可变大小块编码的快速模式决定的方法,参考当前编码运动块与至少一个参考运动块之间的空间和时间相关性,以决定用于编码当前编码运动块的最佳模式。 所述至少一个参考运动块包括当前运动块的至少一个相邻运动块和/或位于与当前图像中的当前编码运动块的位置相对应的位置处于先前图像帧中的先前运动块 帧。 从至少一个参考运动块获得至少一个块大小模式。 在使用至少一个块大小来编码当前运动块之前,该方法进一步检查至少一个块大小模式的可靠性。
