提出了一种消除低照度、中慢速运动视频序列中噪声的方法。在编码的不同阶段采取不同的滤波方法:在预测编码阶段,对于帧内块利用空域相关信息采取高斯去噪方法,对于帧间块利用时域相关信息采取运动补偿去噪策略;在变换编码阶段,采取8×8整数DCT变换的方法,在量化中去除高频噪声。实验结果表明了方法的有效性,降低了码流。 A method of eliminating noise in low-light and medium-speed moving video sequences is proposed. At different stages of coding, different filtering methods are adopted: In the prediction coding stage, Gaussian denoising method is used for intra-block using spatial correlation information, and motion compensation denoising strategy is used for inter-block correlation using time-domain correlation information. In transform coding stage , 8 × 8 integer DCT transform method to remove high-frequency noise in the quantization. Experimental results show the effectiveness of the method and reduce the code stream.
