Or is there are anything wrong in your code about MS transform?
from contrique.
MS-color space as well as other color spaces are included to provide complementary information. Thus, using them as standalone does not give the best result. MS colorspace performs worse if you just use it without any other colorspace since it only contains high pass information which is not enough to make quality predictions particularly in UGC images since they are highly content dependent. You have to use multiple colorspaces simultaneously to achieve good performance.

And I want to know is local feature essential? Does it have important meaning for MS colorspace? I try to use RGB、Grayscale and MS colorspaces stimultaneously but its result is worse than using RGB、Grayscale simultaneously without using local feature
from contrique.
Local features are beneficial for certain distortion types (might not be applicable to all artifacts). So the performance might degrade if your evaluation data is not sensitive to local changes.

You say just using MS colorspace for training performs worse,but in your paper just using the MS space performs much better than other colorspaces in UGC dataset.Both For KONIQ10k and SPAQ dataset,I can't get such result using MS colorspace or combine with other colorspaces.
from contrique.
I meant using MS space alone performs worse when compared to using multiple color spaces which is what we have shown in the paper.
Regarding results, we have reported the performance for KoNIQ-10k in the paper. If you're trying to replicate the experiments reported in the paper please email me directly indicating what issues you're facing along with the details.
