Summary: | The invention provides a method and device for eliminating nois. The method for eliminating noise disclosed in an embodiment of the invention comprises decoding a bitstream encoded with a first codec, acquiring Quantization Parameter (QP) values determined in a process of encoding the bitstream with the first codec, detecting a frame with noise by using the QP values and inputting the frame with noise to a predefined noise filter.
本发明提供种噪声消除方法及噪声消除装置。本发明的实施例的噪声消除方法包括:对通过第编解码器编码的比特流进行解码的步骤;获得在通过第编解码器编码的过程中确定的量化系数(QP:Quantization Parameter)的步骤;使用量化系数来确定含有噪声的帧的步骤;以及将确定为含有上述噪声的帧输入到预定噪声滤波器的步骤。 |
