Automated image registration. Registrationimation was too much of a mouthful.

This repo contains the code used for my blog post Alignimation: Differentiable, Semantic Image Registration with Kornia. This code is not really meant to be used as a general purpose library; rather, this just just my collection of code that I happened to put into a package.

Maybe one day I'll turn this into a general purpose library for aligning things, but today is not that day.

Installation

If you do want to use the code for some reason, you can install the dependencies with poetry by cloning the repo and running poetry install. The code has been run with python 3.8. I don't know if it works for other versions.

If you don't feel like installing poetry, you can try installing the following libraries with pip and praying that the versions work together:

matplotlib
torch
torchvision
kornia
tqdm
facenet-pytorch

Usage

You can load all images in a path with alignimation.io.load_images. The images will be loaded in sorted order of the date that they were taken.

The main function for creating the following gif was alignimation.base.alignimate.

body

To create the below gif tracking my face, I first ran alignimation.face.main to generate the facial keypoints and then ran alignimation.base.alignimate

face

Tests

I didn't feel like writing any tests

  • What if keypoint names are not given?

    What if keypoint names are not given?

    Thank you for sharing such an amazing work of yours!

    I'm studying image registration and always wondered how I can replace optimization part with PyTorch.

    Your work is exactly what I've been looking for.

    I have a question regarding a mapping process.

    Using segmentation model, you obtain keypoints and use them for mapping.

    What if keypoint names, such as left ear, are not provided?

    Let's say we're using all keypoints from the segmentation and trying to register the image.

    Does the algorithm work fine or is there any other approach?

    (I'm currently working on a case in which no keypoint name information is given, but only arbitrary keypoints are given.)
