shifter notebook

A way to determine the direction in which you need to move the image so that the image matches the specified image. Use SIFT technology.

Quickstart

Place the image in the "data" folder query_1.jpg and target_1.jpg -> run detect_shift.ipynb

Description

1. use sift for detect keypoint on target and querry image.
2. use knnMather; Match target keypoint and querry keypoint.
3. Calculate dX=sum(dx1, dx2, .. ), dY=sum(dy1, dy2, .. ) ->cos, sin, and show shift.

keypoint = (x, y)

dx = x2-x1; x2 - target x, x1 - target y;
