I use SIFT, and I want to find the angle of inclination of an image compared to two reference images, in short:
I have 3 images :
Image x: input image
Two images 1 and 2, reference images that are very similar.
My goal is to find the angle of rotation between the image x and a combination between the two images 1 and 2. My problem is that I dont know how to combine the two images of the database to compare them with to the image x.
The purpose of the combination is to extract a vector Keypoints and Mat descriptor from the 2 keypoint vectors and the 2 Mat descriptors.
