DeOldify – How to Use AI and Setup Image Colorization Process

DeOldify is one such application which includes pre-trained weights, allowing you to colorize black and white images or video with minimal effort.

In this guide, I will explain how you can colourize old images and videos using deoldify and ai image colourization.

What is Deoldify?

Colorizing images has become more than an art technique and is now a real-world application, as more people continue to add extra details in their images. More costly, hectic and time-consuming methods of colorization have now been replaced with advanced technologies such as machine learning solutions. These may not be rendered as optimal solutions, but they offer impressive results. DeOldify is one such machine learning as a service which includes pre-trained weights, allowing you to colorize black and white images or video with minimal effort!

DeOldify Download Github Repository:

DeOldify is an open-source deep learning model, created by Jason Antic, to help colorize and restore old and grayscale images. This deep learning model is responsible for adding new life to dull and dark old images and film footage. Adding details into old images has become easy with DeOldify, which uses the machine learning technology. Use pre-trained weights to add color to grayscale images or videos with the most minimal effort.

AI Colorization Process

The world has always been full of color but until recently we lacked the technology to capture its beautiful colors and the pictures were mostly black and white. But these can also be colorized to achieve realistic results, using AI. This method involves training a Convolutional Neural Network (CNN) on a large number of lab colorspace photos. The colospace method corresponds better with the human visual system than RGB. The images are made up of three channels and the predictive model is trained to predict a (red-green) or b (blue-yellow) depending on the lightness channel (input). By recombining into a colorized image, it can be converted back to RGB. 

This technique can offer good results on a number of materials, such as landscapes and countryside. However, results may not be the same for more complicated scenes. Even then it is less tedious than manual techniques and offers better results.

How to Use and Setup Deoldify (Step by Step Process)

For those who are looking to try it themselves; connect to the directory you want DeOldify to be placed in, then clone it via DeOldify.

  1. After doing this, connect to the freshly created DeOldify directory to create a new “models” directory for your pre-trained weights.
  2. Now download the pre-trained weights via the command line: wget -O ./models/ColorizeArtistic_gen.pth
  3. You can also manually download pre-trained weights in the DeOldify, in case you already do not have them.
  4. Now install dependencies:
  5. pip install -r requirements.txt
  6. Once this is done, open the project in a Jupyter Notebook. 
  7. You should now be able to open the ImageColorizer.ipynb file and colorize from there.

DeOldify Reddit Reviews 

DeOldify has been discussed by numerous members on Reddit. Most of the members have shared their positive reviews and experiences with DeOldify on Reddit. Some members have also shared their work with other members to show them the quality of work they can get with DeOldify. Furthermore, members also share any updates or information they receive regarding DeOldify. One such example of this is a discussion, posted about two months ago, about a tweet shared by the creator of DeOldify, that stated that the new versions of this software will not use GANs anymore, but something else related to the concept of perceptual loss applied in super-resolution. This discussion had comments from other users too, who gave in their two cents regarding this new update.

From the Reddit reviews, it is safe to say that people generally like the DeOldify platform for editing their old and grayscale pictures. However, there are numerous other options available on the market, as mentioned above.

How do you color old photos?

Colorizing black and white photos is not a new phenomenon, from being colored by hand in the past, these are being done with digital ai image processing solution or like Photoshop and other computer vision applications that produce more realistic and historically accurate results. Simple graphic tablets and a pen can also be utilized to colorize images. For this, the image has to be restored first, including the removal of stains and scratches. Then it just comes down to choosing the right tones and adding multiple layers to achieve higher accuracy and better feel. This process can take a couple of hours or even days. A good understanding of light can help produce meticulous results.

What is image colorization?

Image colorization is the process of converting a grayscale (black and white) image into a colorized image by adding colors and tones that can bring realistic accuracy.

How do you use DeOldify if you don’t have any AI experience?

Since DeOldify is a pre-trained model, which means it has been fed large amounts of input already; it can be used by anyone, regardless of their level of AI exposure.
