    • A video encoder and corresponding method are provided for encoding video signal data for an image block and a particular reference picture index to predict the image block, where the encoder (100) includes a fast search block motion estimator (180) for providing motion vectors corresponding to the at least one particular reference picture, the motion estimator comprising a fast search block matching portion for performing fast search block matching while excluding non-optimal search points in accordance with a comparison of a normalization of the image block pixels against a normalization of the reference picture pixels, the fast search block matching portion having an output responsive to the at least one particular reference picture; and the corresponding method (200) includes receiving a substantially uncompressed image block (212), block matching (214) the image block in correspondence with at least one particular reference picture while excluding non-optimal search points in accordance with a comparison of a normalization of the image block pixels against a normalization of the reference picture pixels, computing (216) motion vectors corresponding to a difference between the image block and the at least one particular reference picture, and motion compensating (218) the at least one particular reference picture in correspondence with the motion vectors.
    • 提供了一种用于对图像块的视频信号数据和特定参考图像索引进行编码以预测图像块的视频编码器和相应方法,其中编码器(100)包括用于提供对应的运动矢量的快速搜索块运动估计器(180) 所述运动估计器包括用于执行快速搜索块匹配的快速搜索块匹配部分,同时根据所述图像块像素的归一化与所述图像块像素的归一化的比较排除非最佳搜索点 参考图像像素,所述快速搜索块匹配部分具有响应于所述至少一个特定参考图片的输出; 并且相应的方法(200)包括:接收基本上未压缩的图像块(212),对应于至少一个特定参考图像的块匹配(214),同时根据标准化的比较排除非最优搜索点 相对于参考图像像素的归一化,计算(216)对应于图像块和至少一个特定参考图像之间的差的运动矢量,以及运动补偿(218)至少一个特定参考图像 与运动矢量对应。
