Hi guys!

I have a question. So I am trying to implement SIFT.

My question is regarding inter-pixel distance. I think after downsampling the number of pixels change but the inter-pixel distance remains the same. But I am reading the paper 'Anatomy of SIFT' which states that after downsampling(subsampling) by 2 the inter-pixel distance doubles.

Am I missing something?

Thanks!
