Hi! I would like to know what should be the output of a sift descriptor when you are extracting them and saving them to a txt file.
I know that a feature vector consist of an m x 128 matrix. I had already obtained that output but what i am currently in doubt is that are they really the descriptors that i am looking for?
The results of my feature vectors are 0 and 1's only.Are they really only o and 1's?
Attached is my sample vector output
and just a follow up, if i want to save those feature vectors to a text files. What function should i use? Thanks in advance :)
