Revitalize Your Black & White Photos with AI in Python
Written on
Chapter 1: Introduction to Colorization
Have you ever gazed at a black and white photograph and pondered what the original colors might have been? I certainly have, especially while flipping through my grandparents' vintage photo album filled with sepia-toned images from their wedding and family events—these captured moments felt as though they were preserved from over a century ago.
Photography is evolving, and the integration of artificial intelligence is reshaping how we perceive images. This transformation isn't necessarily negative; in fact, it opens up exciting possibilities. Today, deep learning algorithms developed in Python are assisting photographers and artists in various tasks, including eliminating red-eye, adjusting depth of field, and even revitalizing those nostalgic black and white photo collections.
The Art of Colorizing Historical Photos
A growing trend among artists involves breathing new life into iconic black and white images by infusing them with vibrant colors. One notable figure in this field is Danish designer Mads Madsen, who has gained popularity on social media for his project that adds color to historic black and white photographs. His work revisits images of 1950s divas and renowned personalities like Albert Einstein, Charles Darwin, and Mark Twain.
Madsen's journey began in 2012 when he undertook the task of restoring and colorizing portraits from the American Civil War. He quickly expanded his scope to include famous individuals such as Winston Churchill, Elizabeth Taylor, Cary Grant, and Ernest Hemingway, sharing his results on the Tumblr page Colorized History, where he has showcased numerous colorized images.
However, the process of colorizing a single photo using traditional editing software can be labor-intensive, often taking anywhere from thirty minutes to several hours depending on the intricacy of the image and its surroundings. But what if there were a way to achieve stunning results with just a few clicks?
Chapter 2: How AI Transforms Colorization
In this article, I will guide you through the steps of colorizing black and white photos with Python, along with a helpful shortcut for those who may not be familiar with programming.
The Challenge: Identifying Colors in Black and White Images
In black and white photography, determining the accurate colors of objects can be quite challenging. However, deep learning has proven effective in image segmentation, particularly in tasks involving object detection and recognition. By employing deep neural networks (DNNs) on RGB images derived from original black and white files, we can generate outputs indicating the probability of each pixel belonging to various object classes. This significantly aids in identifying where each object is situated in a given scene.
You may have encountered this technology on social media, where a black and white image is overlaid with a color version. Such results are typically generated by AI programs that analyze minute details—like skin texture and clothing—to decide the appropriate colors for different elements of a person's appearance.
While the AI coloring process may not yet be flawless, it can produce remarkably realistic outcomes in mere minutes or even seconds for many images.

Learn to Colorize Photos with Python
If you're interested in colorizing your black and white photographs, this guide is tailored for you. I will demonstrate how to harness artificial intelligence to bring color to your images in just minutes. The entire procedure will be automated, requiring only that you load and execute the provided Python code. You can find the code on GitHub here.
This project utilizes OpenCV and Numpy to colorize your photos or webcam videos. Be sure to include the PySimpleGUI.py file from the project's GitHub repository (minimum version required: 4.26.0.13). For a visual demonstration, check out this YouTube tutorial on how to use AI to colorize black and white photos in minutes.
The second video, "3 Methods to Colorize Black and White Photos using Photoshop & AI," covers additional techniques for photo colorization.
Chapter 3: Conclusion
By utilizing deep learning AI and a few lines of Python code, you now have an effective method for colorizing black and white photos! This approach is fast, user-friendly, and automated. If programming isn't your forte, there are numerous websites that can help you colorize images with just a few clicks. One of my go-to solutions can be explored here.
What are your thoughts on the results? While some details may not be perfect, they are impressive considering the minimal effort required. Perhaps in the near future, the distinction between colorized images created by AI and those manually done will blur even further.
