How to solve the problem of poor matching results in self-built data sets

[yuanjie0217]

Hi, I'm having some problems with image matching using your project. I used my own dataset, but the matching was poor, especially with a small number of iterations, and the resulting matched images were distorted. I followed the documentation, but the problem persists. I would like to ask for some suggestions to improve the quality of image matching, especially on how to avoid image distortion.
