A Chrome extension that adds a 3d photo effect to instagram pages.

A chrome extension that adds depth parallax (an effect similar to Facebook 3D photos) on images from instagram profile pages.

It uses 3d-photo-inpainting running in Colab (free GPU) and Cloud pubsub/storage for communication.

⚠️ Word of caution!

🧪 This project is highly experimental and requires a strong knowledge of the Google Cloud Platform to setup & run.

Architecture

architecture

This extension works by communicating with a Colab notebook running as GPU worker to compute the 3D inpainting videos.

For this extension to work, there are 2 other applications that must be running:

  1. The Colab notebook. It must be openned in another tab with the last cell running.
  2. The proxy service. It must be running (either remotely or on your computer) to receive HTTP requests from the extension and turn them into PubSub messages that the Colab listens to.

Setup the GCP Project

Create a GCP project

First create a project on the Google Cloud Platform. Then install the Cloud SDK and initialize it in your local machine with gcloud init.

Alternatively, you can also use Cloud Shell.

In a terminal window, set the local default project:

export PROJECT_ID=<your gcp project id>
gcloud config set project $PROJECT_ID

Create a service account for colab to be able to access cloud pubsub & storage.

It will create a insta3d-colab-key.json file that you must upload on the Colab to authenticate the notebook with your project.

export COLAB_SA=insta3d-colab
export COLAB_KEY_FILE=./insta3d-colab-key.json
./scripts/create_colab_key.sh

Create the Pubsub topic and subscription

export TOPIC_NAME=insta3d
./scripts/create_pubsub.sh

Enable CORS on your bucket

For the extension to be able to load the images generated by the colab, the CORS must be enabled on a Cloud Storage Bucket.

One way to do so is to create a file cors.json

[
  {
    "origin": ["*"],
    "responseHeader": ["Content-Type"],
    "method": ["GET"],
    "maxAgeSeconds": 3600
  }
]

And apply it to your bucket by running:

export BUCKET_NAME=<your-bucket-name>
gsutil cors set cors.json gs://$BUCKET_NAME

/!\ This will enable the CORS on the entire bucket.

Run the proxy service locally

(Recommended) Create a virtual environment

virtualenv venv
source venv/bin/activate

Install the dependencies:

pip install -r proxy/requirements.txt

Start the proxy:

export GOOGLE_APPLICATION_CREDENTIALS=$(pwd)/insta3d-colab-key.json
python proxy/main.py

Run the Colab

Open the notebook in Colab and follow the instructions. Make sure you've activated a GPU Runtime.

Load the extension & enjoy

Phew, when all that is done, it's time to load the extension and profit!

  • Navigate to chrome://extensions
  • Click the Load unpacked button
  • Select the "extension" folder from this repo.

It should add a new icon in your extensions bar that you can use to trigger the extension. Keep an eye on the console to check for eventual errors.

Changes with the original 3d-photo-inpainting

  • Update argument.yml to use custom path + smaller size + custom fps/duration
  • Update straight-line and circle paths in utils.py
  • Set ffmpeg to create 1 keyframe per frame in mesh.py
