Hey all. twice now ive coded sift from scratch, but mine never gives as good results, and the one part i used a library for (convolution for DoG) didn't give same results given same params as example image tests online. I need this one small part for a much, much, larger project, and I want a neasy fix for this. What libraries don't use openCV but can also perform feauture point detection and matching. Any help appreciated. I am new to python, so I would prefer not to mess with compiling the libraries with cmake or any other 3rd party software. I use notepad ++ and the default interpreter for python 3.6 on windows 10. Any help appreciated, i have spent days googling, and even tried many diffrent languages. I'm not asking for lack of effort, every google suggestion seems to have a "gotcha" that requires backdated versions of libs or compiling binaries or only works on linux.
