 # Performance
 * Detector repeatibility: 0.67
-* Homography estimation on **HPatches-V**: 0.698(corresponding result proposed by rpautrat's model is 0.712)

 (Much better performance can be achieved, [0.725](https://github.com/shaofengzeng/SuperPoint-Pytorch/issues/6), if using the data generated by rpautrat's magicpoint. Our magicpoint generally produces more points, this may be the reason for the low accuracy. In other words, you may achieve better performance by setting proper values for `det_threshold`, `nms` and `top_k`. )
