[18709817706]

Hello, I'm running python extract_features.py --image_list_file image_list_qualitative.txt --multiscale ，generate descriptors.npy keypoints.npy scores.npy document.After I visualized the file descriptors.npy keypoints.npy scores.npy.The resolution of the generated picture is very low, only a blurred image and a straight line can appear, what is the problem.Looking forward to your reply
