Hi!
Sorry for disturbing you. I am a bit confused about the patch size setting in your paper.In L2-Net and HardNet,patch size is 32X32,but your patches seem to be 12σ × 12σ. I have seen LIFT. But I still do not fully understand the relationship between patch size in pixel and σ.Could you give me some suggestions？

What is the patch pixel size setting in your project？

Sorry for the late response. Basically, σ denotes the feature scale, which can be obtained from a keypoint detector that constructs image pyramid, such as SIFT. The size of a patch is always 32x32, but the sampling size is 12σ × 12σ. Perhaps the code will better explain its effect.

I also write an example to address this issue. Please refer to this discussion.
