ACMMP algorithm on ETH3D dataset #8

Hi, in the paper Planar Prior Assisted PatchMatch Multi-View Stereo you say maybe you will combine ACMP with multi-scale strategy in the future, is the algorithm ACMMP the implementation? It looks like so from the name.

If you do not know about ACMMP, do you implement ACMP + ACMM yourself? Will it be much better than ACMP? And how about the speed?

GhiXu commented 3 years ago

Yeah, ACMMP is the implementation of ACMP with multi-scale strategy. The F1 score of ACMMP is better than ACMP, but its efficiency is worse than ACMP. The related comparison can be seen from the ETH3D website.

Thank you for your immediate reply!

Hi, I still have a question, if my image resolution is rather low, for example no more than 640, then using multi-scale strategy will not promote the result, right?

GhiXu commented 3 years ago

As can be seen from the results on the low-res ETH3D many-view dataset, I think that multi-scale strategy can also improve the performance. However, compared with high-res input, the improvement for low-res input is relatively limited.
