About SURF descriptors vector information
Hello, I'm korean student. Maybe you can not understand my word. really sorry, So I'm trying to make a program that can match books in different pictures. I use SURF algorithms, and BF matcher.
MY point is How can i get vector information about keypoints by SURF or SIFT descriptors ?
There are multiple types of information. Do you want a vector of the locations, or the descriptors, or something else?
"a program that can match books in different pictures" --- NO. you can't use SURF featuredetection & matching to detect several different objects. you can only find the position / orientation of a single, known part of the scene.
