1·The JND model is one of classic metrics in objective perceptual video quality research.

基于全参考的JND模型是视频图像质量客观评价算法中的一个经典算法。

2·Against the bit error when the picture is compressed, with JND model in order to keep invisible, a new bit error correction method is proposed based on extraction-comparison.

针对图像压缩时所导致的误码，利用JND模型，提出了一种新的基于提取对比的误码修正算法。
