    • The invention relates to a method for generating for at least one macroblock of a high resolution image at least one motion predictor from motion data associated to macroblock(s) of a low resolution image. The method comprises the following steps: - defining a virtual structure made up of non overlapping macroblocks, called virtual base layer macroblocks; - identifying for the high resolution macroblock corresponding virtual base layer macroblocks in the virtual image on the basis of the location of the high resolution macroblock within the high resolution image and on the basis of the ratios of low resolution and high resolution images dimensions; - deriving, for each identified virtual base layer macroblocks, motion data from motion data associated to at least one macroblock of a corresponding low resolution macroblocks pair on the basis of the field/frame mode of the corresponding low resolution macroblocks pair and on the basis of the field/frame mode of the high resolution macroblock; - resampling motion data associated to the corresponding virtual base layer macroblocks so as to generate the at least one motion predictor.
    • 本发明涉及一种用于从与低分辨率图像的宏块相关联的运动数据生成高分辨率图像至少一个运动预测器的方法。 该方法包括以下步骤: - 定义由非重叠宏块组成的虚拟结构,称为虚拟基本层宏块; - 基于高分辨率图像内的高分辨率宏块的位置并基于低分辨率和高分辨率图像尺寸的比率来识别虚拟图像中的高分辨率宏块对应的虚拟基本层宏块; - 基于相应的低分辨率宏块对的场/帧模式,并且基于相应的低分辨率宏块对的场/帧模式,针对每个所识别的虚拟基本层宏块,从与相应的低分辨率宏块对的至少一个宏块相关联的运动数据导出运动数据 高分辨率宏块的场/帧模式; - 对与相应的虚拟基本层宏块相关联的运动数据进行重新采样,以便生成所述至少一个运动预测器。

    • The invention relates to a method for reconstructing a picture that is part of a sequence of pictures, from coded digital data, representative of said current picture. It comprises the following steps: - construct (30, 34, 32, 36), for each picture block, first and second prediction blocks (from a first picture (h) and a second picture (I2) previously reconstructed, and - calculate (38), for each block, a confidence value representative of the proximity between the visual content of the first predictive block and the visual content of the second predictive block, and - reconstruct each block: - from a part of said coded digital data representative of said block and initial auxiliary data calculated from the first and second predictive blocks if the block confidence measurement is greater than a predetermined threshold, and - from other data if the confidence measurement is less than or equal to the predefined threshold.
