Not working with SIFT instead of OPENCV_SIFT

[chekirou]

Hi,
I would like to use models.features.sift.SIFT instead of OPENCV_SIFTas a feature extractor but the superglue matcher doesn't work with this configuration. Even if the model is trained using the features from OPENCV_SIFT, shoudn't the two versions of sift compute the same features given the same parameters ? Here are the configurations i used :

features:
  name: 'SIFT'
  descriptor_dim: 128
  parameters:
    max_keypoints: 2048
    nms_diameter: 9
    rootsift: True
    descriptor_dim: 128 

With SIFT no matches are found.
