I've been trying to speed up some of my feature extraction steps and it has taken a bit to test out due to large datasets, but just from batch latency, it looks like only SIFT has GPU acceleration sup…

I am exploring the use of COLMAP's descriptor with SIFT_ROOT normalization and VLFEAT's SIFT descriptor with SIFT_ROOT normalization. My initial tests show that both are performing correctly. However,…

### Description:
It seems that `skimage.feature.SIFT` currently only supports detecting and extracting keypoints using SIFT. However, [OpenCV](https://docs.opencv.org/4.x/d0/d13/classcv_1_1Feature2…

### What:
**Removal based on feature matching** involves detecting and analyzing key features in images to identify and eliminate duplicates or overlapping images. This technique uses feature detec…

SIFT descriptors from visual features that look similar should naturally cluster. It remains to be seen whether SIFT descriptors from the same class would cluster. This hypothesis should be tested by …

Hi,
Is it possible to use other feature extraction instead of SIFTGPU?
I found out most people import their features or descriptors to the database. I was wondering how to edit the extraction.c…

The local feature extractor SIFT based DOG extractor class model in hloc/extractors/dog.py seems to be now broken becuase of the update in the pycolmap.
With the latest pycolmap 0.6.1, pycolmap.sift.…

Hi, I have an issue evaluating the descriptors using --descr-dir argument.
I've downloaded the sift descriptors and saved in **_root/data/descriptors/sift/_**. And when I'm in the folder of _**pyth…
