摘要
采用一种基于模糊推理的方法来对块编码的灰度图像进行帧内误码恢复。在丢失块周围像素匹配的基础上采用模糊推理对匹配的结果进行模糊分类,并对匹配准确度低的块进行改进的像素逐点修正处理,从而达到误码恢复的目的。实验结果标明,该方法可以获得比较满意的结果。
A new fuzzy reasoning based technique of information-restoration for the block-based gray images was proposed in this paper. It aimed at intra frame error concealment. To recover from the error code, the pixel matching was implemented firstly. Then the fuzzy reasoning was applied to classify the results of pixel matching. Finally the developed pixel correction was processed to modify the pixels of the blocks with low RED （recover exactness degree）. The experiment results show the effectiveness of the proposed scheme.
