@lllllllllllll-llll (982-779)/29=7, 你所说的982张图像中重复了7次参考图像，具体的是5种失真中压缩的两种失真各分了两组实验。
一般都是只用失真图像作训练的（跟模型准确率是否提升没有关系）。

如果你非要加上有标注的参考图像（实际上不算标注了，因为参考图像的dmos都是0了），可以只加上一组参考图像就行了（但如果没有特别的情况需要这么做的话，就是现行的779张图像就行了。），没必要重复7次。

我不清楚为什么有个别研究者要把这些参考图像算上，因为原数据集论文TIP2006作者写的也是779张图像。
如果重复7次的参考图像都算上的话，那么就会出现很多预测结果一样的结果，这个时候是可能导致你计算的指标偏更好的。
