摘要： A method of temporal error concealment for generating the image data of the missing macro-blocks in the current frame by using the previous frame and the correct data of the current frame is disclosed. The method includes the steps: first using Optimal Regression Plane to estimate the space motion vectors for each block in the missing macro-blocks; selecting appropriate motion vectors from the estimated space motion vectors and the correct temporal motion vectors in the pervious frame as the candidate motion vectors; dividing the missing macro-block into sub-blocks with optimal size; fine tuning the candidate motion vectors as the predicted motion vectors; and using the predicted motion vectors to generate the predicted image data for the missing macro-block and further concealing the effect of the missing macro-blocks upon the image quality of the current frame. The method reduces the computation time, speeds up the process, and improves the image quality.

摘要： A method for performing motion estimation is provided. The method includes the following steps: selecting a current block in a current frame; obtaining motion vectors and residual data of a plurality of neighboring blocks adjacent to the current block; setting a predetermined threshold value according to the residual data of the plurality of neighboring blocks; comparing the current block with an initial reference block in a reference frame to obtain an initial comparison result, and comparing the predetermined threshold value with the initial comparison result; determining a predicted motion vector of the current block according to the motion vectors of the plurality of neighboring blocks if the initial comparison result is larger than the predetermined threshold value; and performing a block-matching operation in a search window corresponding to the predicted motion vector to determine a corresponding reference block which best matches the current block.
摘要翻译：提供了一种执行运动估计的方法。该方法包括以下步骤：选择当前帧中的当前块; 获取与当前块相邻的多个相邻块的运动矢量和残差数据; 根据所述多个相邻块的残差数据设定预定阈值; 将当前块与参考帧中的初始参考块进行比较以获得初始比较结果，并将预定阈值与初始比较结果进行比较; 如果初始比较结果大于预定阈值，则根据多个相邻块的运动矢量确定当前块的预测运动矢量; 以及在对应于预测运动矢量的搜索窗口中执行块匹配操作，以确定与当前块最佳匹配的对应参考块。
