Landmark based and automatic alignment tools

Installation

git clone https://github.com/ElTinmar/alignment_tools.git
conda env create -f alignment_tools.yml

How to use

from alignment_tools.align_affine_2D import AlignAffine2D
from PyQt5.QtWidgets import QApplication
import sys
import cv2

FIXED = cv2.imread('toy_data/image_00.jpg')[:,:,0]
MOVING = cv2.imread('toy_data/image_02.jpg')[:,:,0]

app = QApplication(sys.argv)
window = AlignAffine2D(FIXED, MOVING)
window.show()
app.exec()

GUI

Use mouse wheel to zoom, right-click drag towards the edges to pan, left-click to create a control point and shift-left-click to remove the nearest control point.

Instructions

Place at least 3 control points on each image before computing the control point-based transformation.
Control points are numbered, they need to match between the two images.

Then refine using auto registration (uses ANTs). You may need to click a few times to get it right.

Do auto registration only when you're close enough with control points, otherwise it won't converge.
