    • A method for motion accounting and compensation while encoding allows improvement of the restored image quality. Image is a predicted frame in video sequence. Motion compensation is understood as an error residual signal compressing scheme, executed during video sequence encoding. According to the teachings of the current invention, errors are accounted for during encoding. Error accounting is subtracting the original image from the predicted frame. The error values are written to the output stream compactly with the minimum code length. The stored error values are added to the predicted frame during the decoding process. The method taught herein is applied for all the predicted frames from the video sequence, thereby allowing one to improve the quality of decompressed video film that was compressed with a significant compression ratio.
    • 一种用于编码时运动记帐和补偿的方法可以提高恢复的图像质量。 图像是视频序列中的预测帧。 运动补偿被理解为在视频序列编码期间执行的误差残差信号压缩方案。 根据本发明的教导,在编码期间考虑到错误。 错误计费是从预测帧中减去原始图像。 错误值以最小代码长度紧凑地写入输出流。 存储的误差值在解码过程中被添加到预测帧。 本文教导的方法适用于来自视频序列的所有预测帧,从而允许以提高压缩比压缩的解压缩视频胶片的质量。
