Why does the SIFT algorithm also capture keypoints at points where there is no change in color components?
Why asking image processing in here?
My question is, about image processing. I can't find stackexchange site to ask about image processing, so I asking in here. Image processing is closed at computer ...

What would be a reasonable option for clustering for unknown number of clusters and a lot of outliers?
I am implementing the CV detection pipeline with the use of SIFT and KNN Matcher.
Image keypoints matched to the query keypoints produce the following image:
The matched objects have a lot of key ...

In SIFT, how is the coordinate system being rotated?
I need to understand how SIFT calculates the descriptors for the keypoints.
Intuitively, I understand that it takes each keypoint, calculates the gradients for each pixel in a neighborhood of the ...

Can I use the SIFT feature detector on data other than images?
I know how to use SIFT algorithm for images but I never use it for other kinds of data. I have tabular data (x, y, z, time) where x,y,z is the joint position along x, y, z coordinates. Now, can I ...
